What distinguishes thermal energy from temperature?

• Thermal energy is independent of the object’s mass, while temperature depends on it.

• Temperature measures particle speed, while thermal energy measures total energy from both kinetic and potential sources.

• Thermal energy can be measured on a thermometer, but temperature cannot.

• Temperature is affected by matter states, while thermal energy is not.

Which of the following statements is TRUE about changes in state due to heat transfer?

• Temperature always increases during a state change.

• Temperature remains constant during a state change, such as ice melting at 0°C.

• State changes only occur when particles lose kinetic energy.

• Temperature and state change are unrelated.

Case Study: Imagine you have two cups of water. Cup A contains 200 ml of water, and Cup B contains 500 ml of water. Both are at 50°C. Which of the following statements is true regarding the thermal energy in each cup?

• Cup A has more thermal energy than Cup B because it has less mass.

• Cup B has more thermal energy than Cup A because it has more mass.

• Both cups have the same amount of thermal energy because they are at the same temperature.

• Cup A has more thermal energy because temperature affects thermal energy more than mass.

Which factor does NOT affect an object's thermal energy?

• The arrangement of particles

• The object's mass

• The average kinetic energy of particles

• The color of the object

If two objects are at the same temperature, but one has more mass, what can be said about their thermal energy?

• The object with less mass has more thermal energy.

• Both objects have the same thermal energy.

• The object with more mass has more thermal energy.

• Thermal energy cannot be compared without knowing the objects' shapes.
