P1.3 gas pressure Flashcards
1
Q
what happens if you increase pressure in a gas
A
Decrease in volume compression
2
Q
What happens if you decrease pressure on a gas
A
Volume increases. It expands
3
Q
What happens if you increase temperature of gas at a constant volume
A
- As temp increases particles gain speed as they gain more kinetic energy
- more frequent collisions with more energy
- force and pressure increases
4
Q
Equation for pressure in gases
A
Pressure (Pa)×volume(m3)=constant
5
Q
Calculation of pressure due to a column of liquid
A
Height of columb (m)× density of liquid (kg/m3) × gravity 10 N/kg
6
