A group of students from PNC experiments to measure the temperature of various objects in a room. They find that when two objects are in contact, heat flows between them until thermal equilibrium is reached. Which law of thermodynamics supports their findings? *First law of thermodynamicsSecond law of thermodynamicsThird law of thermodynamicsZeroth law of thermodynamics
Question
A group of students from PNC experiments to measure the temperature of various objects in a room. They find that when two objects are in contact, heat flows between them until thermal equilibrium is reached. Which law of thermodynamics supports their findings? *First law of thermodynamicsSecond law of thermodynamicsThird law of thermodynamicsZeroth law of thermodynamics
Solution
The law of thermodynamics that supports the students' findings is the Zeroth law of thermodynamics. This law states that if two systems are each in thermal equilibrium with a third, they are in thermal equilibrium with each other. This implies that heat will flow between objects until thermal equilibrium is reached, which is what the students observed.
