#105, Quick Check: Thermal Energy and Temperature

There will be less friction between the molecules

The particles will lose thermal energy

The particles will become closer together (thermal contraction)

The particles will speed up.

Increasing the distance between the particles that make up the soup (thermal expansion)

Putting the soup in the refrigerator

Heating the soup up for one minute on the stove

Doubling the amount of soup in the bowl

Because there is more friction between the molecules in large pot of water

Because the larger one has more molecules to transfer the energy through

Because there is more thermal energy in the small pot of water

Because the average kinetic energy of the particles in the large pot is greater

Particles lose energy when they collide with higher energy particles.

Particles lose energy when they collide with lower energy particles.

Particles lost energy when gravity pulls particles down towards Earth.

Option 1

Option 2

Option 3

Option 4

Substance A has a greater average kinetic energy of its particles but the same amount of thermal energy as substance B.

Substance A has greater thermal energy but the same average kinetic energy of its particles compared to substance B.

Substance A has BOTH a greater thermal energy AND a greater average kinetic energy of its particles compared to substance B..

The temperature of the substance A would increase.

The thermal energy of substance A would increase.

The molecules in substance B would transfer their coldness to the molecules in substance A.

The molecules in substance A would transfer their energy to the molecules in substance B.

colder than room temperature then it would warm up again

colder than room temperature (less than 20°C)

the same temperature as the air (equal to 20°C)

warmer than room temperature (greater than 20°C)
