Answer: increases 
Explanation: 
The expression for an Ideal Gas is: 
 
Where: 
 is the pressure of the gas 
 is the volume of the gas 
 the number of moles of gas 
 is the gas constant 
 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.
