Thermal Equilibrium and Heat Transfer Quiz

What is thermal equilibrium between two objects?

• When heat flows from a colder object to a hotter object.

• When objects have different temperatures and heat flows at the same rate.

• When there is no net flow of heat between objects with the same temperature.

• When objects have different temperatures but no heat transfer occurs.

How does heat transfer occur between objects with different temperatures?

• Heat does not flow between objects with different temperatures.

• Heat flows only from the object with lower temperature to the one with higher temperature.

• Heat flows at the same rate in both directions.

• Heat flows from the object with higher temperature to the one with lower temperature.

How does thermal equilibrium apply to refrigerators?

• The food remains at a constant temperature in the refrigerator.

• The refrigerator cools the food by increasing its temperature.

• Heat is transferred from the refrigerator to the food until they reach different temperatures.

• Heat is transferred from food to the refrigerator until both reach the same temperature.

What happens when a thermometer reaches thermal equilibrium with a patient's body?

• The thermometer's temperature matches the body's temperature.

• The thermometer's temperature remains unchanged.

• The thermometer's temperature decreases rapidly.

• The thermometer's temperature increases significantly.

What is the difference between thermal energy and temperature?

• Thermal energy is a form of energy, while temperature is a measure of hotness.

• Temperature is a form of energy, while thermal energy is a measure of hotness.

• Thermal energy is measured in Kelvin, while temperature is measured in Joules.

• Temperature is the sum of kinetic and potential energy, while thermal energy is the average kinetic energy.
