How can you tell which one the two sample will release energy in the form of heat when the two sample are in contact?
the hotter sample because energy flows from hot to cold until the two are the same temperature.
Compared to the particles in a hardened lava sample the particles in a liquid lava sample?
Have less kinetic energy
When 5.10 kJ of heat energy is added to a 430 g sample of silver?
When 5.1 kJ of heat energy is added to a 430 g sample of silver, find specific heat of Ag
An increase in the average kinetic energy of a sample of copper atoms occurs with an increase in what?
Temperature

no
What happens to a sample of matter when its particles lose kinetic energy?
A loss of kinetic energy in the atoms or molecules of a sample of matter will result in the cooling of the sample. That sample will get colder as remove thermal energy from it. The atoms/molecules of a substance have kinetic energy associated with them. This kinetic energy is the result of atomic and/or molecular motion. As a sample of matter cools, the atoms and/or molecules will lose mobility. Loss of mobility and vibrational energy, which are forms of kinetic energy, will become apparent when thermal energy is removed from the sample.
How do you make a pure sample of xenon?
Liquefy air and then allow it to heat up - collecting the gas through fractional distillation.

What types of energy would exist in both a solid sample and a gas sample of the same monatomic substance?
kinetic energy from translation
How can you tell which one the two sample will release energy in the form of heat when the two sample are in contact?
the hotter sample because energy flows from hot to cold until the two are the same temperature.
What type of energy is associated with random motion of particles in sample of gas?
thermal energy or kenetic energy
What type of energy is associated with random motion of particles in a sample of gas?
thermal energy or kenetic energy
1. 10 J of heat are removed from a gas sample while it is being compressed by a piston that does 20 J of work. What is the change in thermal energy of the gas Does the temperature of the gas increase?
10 JoulesConservation of energy, assuming there are no other losses in the system, and 20 Joules are introduced by compression, and 10 Joules are removed by heat transfer, the remaining 10 Joules must be absorbed as increased thermal energy of the gas.
