Sixth-grade students conduct a laboratory experiment investigating the flow of thermal energy. They place a sealed plastic bag filled with water at 60°C into a beaker filled with an equal amount of water at 80°C. They then put the beaker with the plastic bag in an insulated container.
Based on the flow pattern of thermal energy, what can students predict will most likely happen in about an hour?
A. Thermal energy will flow from the cooler water in the plastic bag to the warmer water in the beaker so that the temperature of the water in the beaker will be 60°C and the temperature of the water in the plastic bag will be 80°C.
B. Thermal energy will flow from the warmer water in the beaker to the cooler water in the plastic bag so that the temperature of the water in the plastic bag will be 80°C and temperature of the water in the beaker will be 60°C.
C. Thermal energy will flow from the warmer water in the beaker to the cooler water in the plastic bag so that the temperature of the water in both the plastic bag and the beaker will be 70°C.
D. Thermal energy will flow from the cooler water in the plastic bag to the warmer water in the beaker so that the temperature of the water in both the beaker and the plastic bag will be 70°C.

Explanation:
Reactant- a substance that takes part in and undergoes change during a reaction.
Product- a substance produced during a natural, chemical, or manufacturing process.
Precipitate- 1. to separate from a solution as a precipitate. 2. to fall to the earth's surface as a condensed form of water; to rain, snow, hail, drizzle, etc.
Precipitate has different meanings so I didn't really know about which one, but tell me if I'm wrong :)
Answer:
Reactant: a substance that takes part in and undergoes change during a reaction.
Product: are the species formed from chemical reactions. During a chemical reaction reactants are transformed into products after passing through a high energy transition state.
Precipitate: a solid formed by a change in a solution, often due to a chemical reaction or change in temperature that decreases solubility of a solid

BOTH acids and bases
A) turn red litmus blue
B) are a component of soaps
C) donate protons to solution
D) conduct electricity in water
Answers
Answer:
Hello There!
Explanation: Your Answer will be, D) conduct electricity in water.
Both acids and bases conducts electricity and water.
When acid dissolves in water, they are good electrolytes.
When bases dissolves in water they are good electrolytes.
Electrolytes are liquid or molten substances that are able to conduct electricity.
they conduct electricity by the use of their ions in solution.
Since acid and bases ionize in solution, they will conduct electricity.
An acid is a substance that produces excess hydroxonium ion in solution.
A base produces excess hydroxyl ions in solution. Hope This Helps!

Energy and Temperature Activity Worksheet
Instructions: Follow the directions below to complete part one and part two of this activity. You will submit both parts once completed.
Note: You are not performing the experiment—only designing it.
Introduction
The purpose of this assignment is to design an experiment that another student could follow and use to test whether land or water heats faster.
You will complete the following:
Part One: Experimental Design. Plan out an experiment by answering the guiding questions below.
Part Two: Design a Lab Report. Write the outline of a lab report so that another student could complete the experiment by using the materials listed below:
sand
water
heat lamps
thermometers
cups
Part One: Experimental Design
In this section, you will think about what type of experiment to set up. Remember, you are NOT completing the experiment, only designing it. If you want to review the scientific method first, use this tutorial. Use these guiding questions to help you design the experiment. Answer each question below:
What hypothesis will the experiment test?
What are the variables?
What purpose would the sand serve?
What purpose would the water serve?
What purpose would the heat lamps serve?
What purpose would the thermometers use?
How can you use these materials to test whether land or water heats faster?
How would you compare whether land or water heats faster?
Within a 24-hour period, at what three points should the temperature be taken? Why?
What would an effective conclusion need to include?
Part Two: Design a Lab Report
Once you have designed the experiment, you must write out the instructions so another student could act as the experimenter and follow them. Fill in the following elements of this lab report as described in italics below.
Lab Report
Objective
Explain the purpose of your lab.
Procedure
List the experiment procedures. Some steps have been filled in for you. You may need to adjust the numbers to match the steps you decide on.
Identify the variables.
Write out your hypothesis in an if/then format.
Gather your materials.
Analyze the data.
Write your conclusion.
Data Analysis
Label a data table so that the experimenter can record observations for the sand and water temperatures at various points.
Conclusion
Explain what the experimenter should include in this section to show how the data proved the hypothesis.

Answer:
the ground would heat up slower than the sand because it has lots of moisture so sand would heat up faster than any thing other than lava

Answer:
75% straight
50% bent
Explanation:
because the Punnett Squares work that way
think of it as a multiplication table...when 2 numbers come to the middle, they give you the answer just like these squares (they're just smaller)
R + R = RR
R + r = Rr
R + r = Rr
r + r = rr
RR is 25%
Rr is 50% because there are 4 boxes and 2 of them is Rr
rr is 25%
Simpler answer:
I know because 25% + 50% = 75% for the straight root. 25% + 25% = 50% for the bent toot.
Why would the climates of Austin, Texas and St. Paul, Minnesota be different?
(use the map)
a St. Paul is much warmer than Austin due to its closeness to the Great Lakes.
b St. Paul is at a higher latitude than Austin. The farther from the equator you are, the colder it is.
c The Altitude in Austin is much greater than in St. Paul, making Austin much colder
d The climates of both cities are very similar since they are almost lined up north and south of each other.

Explain the correlation between chemical properties and chemical changes. (plz i not sure on the answer so it would mean a lot if you could help me.)
Answers
Answer:
Explanation:
A chemical property describes the ability of a substance to undergo a specific chemical change.
A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances.
Differences
Chemical properties are properties that can be observed or measured when a substance undergoes a chemical change.
Physical properties are properties that can be observed without bringing a chemical change.
Another one
chemical properties; can be used to predict how substances react.
chemical changes; It is mostly used in identifying or describing the substance.
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.

Answers
Answer:Ground
Explanation:The roots help soak up moisture fromthe ground and can also store extra food made from photosynthesis
Photosynthesis occurs and extra food is stored in ground plant tissues in the form of sugars.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.
