3.1 Thermal Energy Is NOT Temperature Reading Qs

What is thermal energy?

• The temperature of an object

• The potential energy of an object

• The total kinetic energy of the molecules in an object

• The average kinetic energy of the molecules in an object

Why did the mug of soup get colder while the bowl of soup stayed warm?

• The mug had a lower total kinetic energy

• The mug had a higher total kinetic energy

• The mug had a higher average kinetic energy

• The mug had more molecules than the bowl

What happens when two objects of different temperatures are in contact?

• The objects gain more thermal energy

• The objects remain at their original temperatures

• The objects exchange thermal energy until they reach the same temperature

• The objects lose all their thermal energy

What is the relationship between thermal energy and the number of molecules in an object?

• Thermal energy is only determined by temperature

• More molecules result in higher thermal energy

• More molecules result in lower thermal energy

• The number of molecules does not affect thermal energy

If two objects have the same average kinetic energy, do they have the same thermal energy?

• Yes, average kinetic energy and thermal energy are the same

• No, average kinetic energy and thermal energy are different

• It depends on the temperature of the objects

• It depends on the size of the objects

Why does the air in the room not change temperature when the soup cools down?

• The air has a higher total kinetic energy

• The air has a lower total kinetic energy

• The air has a higher average kinetic energy

• The air has a lower average kinetic energy
