Thermal energy is transferred to a substance. Which change can occur?

Answers

Answer:

The temperature scale on which water freezes at 0 and boils at 100. Thermal energy that is transferred from one substance to another; moves from warmer to cooler objects. The transfer of heat by direct contact; occurs when energy is transferred by collisions between particles.

Explanation:

When thermal energy is transferred both kinetic and potential energy increases.

What is thermal energy?

Thermal energy is defined as a type of energy which is contained within a system which is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.

Thermal energy arises from friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance whose molecules or atoms are vibrating faster.

These vibrating molecules and atoms collide and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy.There are three types of thermal energy transfer:1) conduction 2) convection 3) radiation

A 1000 kg boulder sits at the top of a 50-meter high cliff. Determine the amount of potential energy possessed by the boulder if the acceleration due to gravity is 9.8 m/s2. The boulder has_______(magnitude/ number)_______(units) of Potential Energy.

Answers

Answer:

490000J

Explanation:

Given parameters:

Mass of boulder = 1000kg

Height of cliff = 50m

Acceleration due to gravity = 9.8m/s²

Unknown:

Potential energy = ?

Solution:

Potential energy is due to the position of a body. It is expressed as;

P.E = mgH

m is the mass

g is the acceleration due gravity

H is the height

Now insert the parameters and solve;

P.E = 1000 x 9.8 x 50 = 490000J

Data:

m = 1000 kg

h = 50 m

g = 9.8 m/s^2

Find:

P.E = ?

Formula:

P.E = mgh

Solution:

P.E = mgh

P.E = (1000)*(9.8)*(50)

P.E = 490000 J

Result:

P.E = 490000 Joule

What would happen if you touched an object that is the same temperature as your hand? Would any heat transfer happen? Explain your answer in 4-5 sentences.

Answers

Answer:

It actually depends.

Explanation:

in the case of a metal ur hand will absorb the heat (but it depends on the temperature, this ans favours hot and cold but not neutral or room temperature), in the case of human to human I think no heat transfer will take place, in the case of liquids(for hot temperature ,it would even for cold but not room).

What does the Law of Conservation of Momentum stare about the momentum in a system in an inelastic collision?

Answers

Answer:

The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

Explanation:

Answer:

For any collision occurring in an isolated system, momentum is conserved. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.

A.a 500-pound car moving at 20 miles per hour
B.a 200-pound car moving at 60 miles per hour
C.a 100-pound car moving at 80 miles per hour
D. a 50-pound car moving at 100 miles per hour

Answers

Answer:

Explanation:

Momentum is the product or multiplication of a body's mass and its speed.

Since all options have the mass and speed in the same units, there is no need for conversion.

A. 20 x 500 = 10000, B. 200 x 60 = 12000

The same goes for the rest!

Go around your house and hit (or tap) ten different objects. The objects should be different shapes and made of different material (choose things to hit that won’t break!). Each object is a different medium for sound. Try to hit each using the same amount of energy. Describe each object that you hit. What is its shape and what is it made of? Then describe how it sounds to you. Does it transmit sound well? Does it absorb sound? Is the sound loud or soft? Is there a “ring” to the sound? Does it sound like a “thunk” or does it sound like a drum? Rank the ten objects from loudest to softest. Draw some conclusions based on your results from Steps 1 and 2. For example, are there a certain shapes or materials that are better or worse media for sound travel?

Answers

Answer:

Explanation:

ball ( it sound like thup thup it is softly harsh in voice )

book ( tak tak it is hard in voice )

bed ( pat pat it is soft in voice )

Door, window, picture, floor,stairs, wall, desk, backpack, paper, bed all of these produce different sound.

What do you mean by sound?

The term sound is defined as an acoustic wave is a vibration that travels through a gas, liquid, or solid transmission medium. In terms of human physiology and psychology, sound is the brain's receipt of these waves and perception of them.

A mechanical disturbance that causes an equilibrium condition to be disturbed and propagates by an elastic material medium.

The vibration of an object creates sound, which travels from one place to another by a medium. Vibration is the phrase used to explain an object's to-and-fro or back-and-forth motion. Vibrations are generated by objects in motion.

Therefore, stairs, wall, door, window, picture, floor, desk, backpack, paper, bed all of these produce different sound.
