A space shuttle is covered with two layers of carbon. The two layers are the same size and have the same number of molecules. When the space shuttle is sitting on the ground, the layers do not touch, as shown in the diagram above. When the space shuttle takes off, the layers move so that they are touching. Use the information in the diagram to answer the question.
How does the temperature of the outer layer compare with the temperature of the inner layer before the layers touch? What will happen after the layers have been touching for a while?
A.Before the layers touch, the outer layer is hotter than the inner layer. Once the layers are touching, the outer layer will transfer kinetic energy to the molecules in the cooler inner layer until both layers reach the same temperature, which will be in between their starting temperatures.
B.Before the layers touch, the outer layer is hotter than the inner layer. Once the layers are touching, the cooler inner layer will gain kinetic energy until the molecules of both layers have an energy of 90, because hotter things increase the temperature of cooler things.
C.Before the layers touch, the outer layer is cooler than the inner layer. Once the layers are touching, the inner layer will transfer kinetic energy to the molecules in the cooler outer layer until both layers reach the same temperature, which will be in between their starting temperatures.
D.Before the layers touch, the layers are different temperatures. Once the layers are touching, kinetic energy and cold energy will transfer between the molecules in the two layers until both layers reach the same temperature, which will be in between their starting temperatures.
Before the layers touch, the outer layer is hotter than the inner layer. Once the layers are touching, the outer layer will transfer kinetic energy to the molecules in the cooler inner layer until both layers reach the same temperature, which will be in between their starting temperatures. Hence option A is correct.
What is kinetic energy?Kinetic energy is defined as the amount of effort an object performs as a result of its motion. The capacity to perform work is kinetic energy's most significant quality of kinetic energy.
When a material is divided, radiation is used to transport the energy, which causes a gradual increase in interior temperature. When two materials are connected together, heat is transferred through conduction, rapidly raising the interior temperature.
Thus, before the layers touch, the outer layer is hotter than the inner layer. Once the layers are touching, the outer layer will transfer kinetic energy to the molecules in the cooler inner layer until both layers reach the same temperature, which will be in between their starting temperatures. Hence option A is correct.

A student determined that a 50mL sample of an unknown liquid had a density of 1 g/mL. A 100mL sample of the same liquid would have a density of 2 g/mL. True or false
Answer: False
Explanation: The density of the liquid will always be the same, no matter how much of the liquid you have.
For example, the density of the water in a pool is the same density as the water in a small cup.

The accepted value for R is 0.08206 L·atm/K·mol or 8.314 L·kPa/K·mol, depending on the unit of pressure used. (Your answer may differ slightly due to rounding.)
How close was your calculation?
Answer:
09.Yl/K.2.Pa/La
Explanation:
(a) The ideal gas constant in Liters, atmosphere, per kelvin per mole is 0.08206 L·atm/K·mol .
(b) The ideal gas constant in Liters, kilopascal, per kelvin per mole is 8.314 L·kPa/K·mol
Ideal gas constant in L.atm/K.molThe ideal gas constant in Liters, atmosphere, per kelvin per mole is determined as follows;
PV = nRT
R = PV/nT
At standard condition;
P = pressure = 1 atmV = Volume = 22.4 L n = 1 mole of gasT = temperature = 273 KR = (1 x 22.4) / (273 x 1)
R = 0.08205 L·atm/K·mol
Ideal gas constant in L·kPa/K·mol,R = PV/nT
At standard condition;
P = pressure = 101.325 kPaV = Volume = 22.4 L n = 1 mole of gasT = temperature = 273 KR = (101.325 x 22.4) / (273 x 1)
