Chapter 13 - Temperature and Thermal Equilibrium Flashcards
1
Q
When did Galileo invent the thermometer?
A
1602
2
Q
What direction does heat flow between objects?
A
Always from hot to cold
3
Q
Temperature
A
Proportional to the average translational KE of an object’s molecules.
4
Q
Thermal Equilibrium
A
Thermal energy flows from a hot object to a cold object until their temperatures are EQUAL and there is no net flow of energy.
5
Q
Zeroth Law of Thermodynamics
A
If 2 objects are each in thermal equilibrium with a 3rd object, then the 2 must be in thermal equilibrium with each other.
