Fourth Quarterly Assessment in General Physics

It states that if Object A is in thermal equilibrium with Object B, and that Object B is in thermal equilibrium with Object C, then, Object A and C are also in thermal equilibrium with each other.

• Thermodynamics

• Thermal Insulator

• Thermal Equilibrium

• Zeroth Law of Thermodynamics

It is a measure of the hotness or coldness of an object that is proportional to the average kinetic energy of the molecules composing the object.

• Warmth

• Humidity

• Heat

• Temperature

It is a state in which heat transfer between two thermal conductors can no longer happen after reaching equal temperatures.

• Thermal Euphoria

• Thermal Equilibrium

• Thermal Conduction

• Thermal Instability

Please refer to Figure 1 illustrating an isolated system of equal masses. Object A’s initial temperature was measured to be 10°C, Object B was initially 40°C and Object C was 30°C. After every 5 minutes, their temperatures were found to change until it was noticed that the readings were already constant. Which of the following is NOT TRUE about the set-up?

• The objects have reached thermal equilibrium.

• Object A’s final is higher than its initial temperature.

• Object B’s final is higher than its initial temperature.

• Object A and B’s last temperature readings are equal to Object C’s.

At which of the following thermally isolated setups would heat transfer be possible?

• 
• 
• 
•
