Heat & Atoms and the KMT of Gases

Ideal gas particles possess potential energy.

• true

• false

Ideal gas particles posses kinetic energy.

• true

• false

Kinetic energy depends on particle position.

• True

• False

If we heat a chemical system, then what happens to its Temperature if all other variables are held constant?

• it stays the same

• it increases

• it decreases

When a bunch of hot particles collide with cold particles, then:

• their respective temperatures do not change after the collision

• the hot particles will transfer motion energy to cold particles

What interaction of particles must occur in order to transfer kinetic energy from one particle to another?

• vibration

• sliding

• colliding

Heat is the amount of energy transferred from one sample of matter to another. What kind of energy is transferred?

• kinetic

• potential

• nuclear

• electrical

Two particle samples move at different speeds. Which one moves faster?

• the one at a higher Temperature

• the one at a lower Temperature

• neither, all the particles move at the same speed

It is reasonable to picture temperature as:

• how hot or cold it is

• the average velocities of particles

• an average motion of partilces

• an average velocity of particles

• all of the above

The direction of heat goes from:

• faster moving particles to slower (in other words: from hot to cold)

• slower moving particles to faster (in other words; from cold to hot)
