Module 5 - 5.1.1 Temperature Flashcards
1
Q
Energy flows from
A
hotter objects/environments to cooler ones
2
Q
Thermal Equilibrium (definition)
A
- two objects in contact with each other at the same temperature are said to be in thermal equilibrium
- there is no net energy flow between the objects
3
Q
Law of Thermal Equilibrium
A
If body A and body B are in equilibrium and body A and body C are in equilibrium then body B and body C must be in equilibrium
4
Q
An absolute scale of temperature is
A
independent of the properties of any specific substance
5
Q
Kelvin is
A
an absolute scale
6
Q
Absolute Zero (definition)
A
- the temperature at which a substance has minimum internal energy
- 0K
7
Q
At absolute zero, the system has (2)
A
- no kinetic energy
- some potential energy
8
