Answer:
When the volume increases or when the temperature decreases
Explanation:
The ideal gas equation states that:
[tex]pV= nRT[/tex]
where
p is the gas pressure
V is the volume
n is the number of moles of gas
R is the gas constant
T is the gas temperature
Assuming that we have a fixed amount of gas, so n is constant, we can rewrite the equation as
[tex]\frac{pV}{T}=const.[/tex]
which means the following:
- Pressure is inversely proportional to the volume: this means that the pressure decreases when the volume increases
- Pressure is directly proportional to the temperature: this means that the pressure decreases when the temperature decreases
