A
-273
3
Q
Degrees Celcius- Kelvin
A
+273
4
Q
Absolute zero
A
- Particles have no kinetic energy
- No pressure exerted
5
Q
What is specific heat energy?
A
Energy required to change 1kg og a substances temperature by 1 degrees celcius.
6
Q
Volume-Temperature
A
- Temperature Increases
- Particles move quicker
- Container wall more often and harder
- Pressure constant the area the particles hit increases, volume increases
7
Q
Pressure-Temperature
A
- Temperature increases
- Particles move faster
- Container wall more often and harder
- Increases force per unit area
- Pressure increases
8
Q
Pressure-Volume
A
- Volume decreases
- Hit container wall more often
- Pressure increase
- Container wall more often exerts bigger force per unit area.
