Question

When the temperature of an ideal gas is increased, the pressure also ________

Answer 1

Answer: increases  

Explanation:  

The expression for an Ideal Gas is:  

$P.V=n.R.T$  

Where:  

$P$ is the pressure of the gas  

$V$ is the volume of the gas  

$n$ the number of moles of gas  

$R$ is the gas constant  

$T$ is the absolute temperature of the gas  

As we can see, there is a direct proportional relation between the temperature and the pressure, which means that if the temperature increases the pressure of the gas increases as well.

However, it is important to note this is fulfilled if and only if the volume of the container where the ideal gas is, remains constant.
