The average kinetic energy of gas molecules increases with temperature true or not?
temperature is the measure of a molecule's average kinetic energy, so yes.
Why is average kinetic energy used when discussing the kinetic energy of a collection of particles?
Average kinetic energy is used when discussing the kinetic energy of a collection of particles because it represents the energy per particle in the system. It provides a way to compare the overall kinetic energy of systems with different numbers of particles. Calculating the average kinetic energy allows for a simpler analysis of the system's overall behavior.
What happens to an objects temperature if the kinetic energy of its particles decreases?
If the kinetic energy of an object's particles decreases, its temperature will decrease as well. Temperature is a measure of the average kinetic energy of the particles in a substance, so a decrease in kinetic energy means a decrease in temperature.
What kind of relationship exists between kinetic energy and temperature?
Kinetic energy is directly related to temperature. As temperature increases, the average kinetic energy of the particles in a substance also increases. This is because temperature is a measure of the average kinetic energy of the particles in a substance.
If all were at the same temperature how would the average kinetic energy of the particles compare an iron cube an aluminum cube and a balloon filled with helium gas?
If the two metals are at the same temperature then the atoms in each would have the same average kinetic energy. Temperature is a measure of the "average energy per degree of freedom". To simplify things somewhat, kinetic energy is one of these degrees of freedom and so if they have the same temperature they have the same kinetic energy. Go to the related link below for a fuller understanding of the connection between kinetic energy and temperature.
Is temperature a form of kinetic or potential energy?
Temperature is a measure of the average kinetic energy of the particles in a substance, so it is a form of kinetic energy.
The average kinetic energy of gas molecules increases with temperature true or not?
temperature is the measure of a molecule's average kinetic energy, so yes.
How does a substance 's temperature change when the average kinetic energy of it's particle increases?
As the average kinetic energy of the particles in a substance increases, the temperature of the substance also increases. This is because temperature is a measure of the average kinetic energy of the particles in a substance. So, when the average kinetic energy increases, the temperature increases as well.
How is kinetic energy related to temperature?
Kinetic energy is related to temperature because temperature is a measure of the average kinetic energy of the particles in a substance. As the kinetic energy of particles increases, so does the temperature of the substance.

An increase in the average kinetic energy of a sample of copper atoms occurs with an increase in what?
An increase in the average kinetic energy of a sample of copper atoms occurs with an increase in temperature. Temperature is a measure of the average kinetic energy of the particles in a substance, so as temperature increases, the particles (such as copper atoms) gain more energy and move faster, which increases their kinetic energy.
What happens to an objects temperature if the kinetic energy of its particles decreases?
If the kinetic energy of an object's particles decreases, its temperature will decrease as well. Temperature is a measure of the average kinetic energy of the particles in a substance, so a decrease in kinetic energy means a decrease in temperature.

What Explain what happens to the average kinetic energy, thermal energy, and temperature of a substance when the particles in the substance slow down.?
The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.
What fraction of the average kinetic energy of hydrogen gas at 100K does hydrogen gas have at 40K?
The average kinetic energy of gas is directly proportional to the temperature. So at 40K, the fraction of the average kinetic energy of hydrogen gas compared to that at 100K would be (40K)/(100K) = 0.4 or 40%.
If you could measure the average kinetic energy of all the particles in a baseball what would you know about the baseball?
Measuring the average kinetic energy of all particles in a baseball would provide information about the temperature of the baseball. The kinetic energy of particles is directly proportional to temperature, so a higher average kinetic energy would indicate a higher temperature.
What does average kinetic energy mean?
Instead of the precise value of the kinetic energy of a system, for example a gas, it is generally more useful to consider its average kinetic energy, since it is absolutely impossible to measure the velocities of all the molecules: <E_k>=1/2 m<v^2>, where <> denotes the mean of the quantity in brackets. More importantly, the average kinetic energy has a very important physical interpretation: it is proportional to the temperature of the system. Temperature itself can be defined as a measure of the kinetic component of the internal energy of a system: according to the equipartition theorem, each independent quadratic energy term corresponds to an average energy of 1/2 kT, where k is Boltzmann's constant; so, in three dimensions the mean kinetic energy of a molecule is 3/2 kT.
