We can increase pressure in more than one way. Consider an ideal gas.
PV=nRT is the ideal gas equation.
Where, P= Pressure
V= Volume
T= Temperature
n= no. of moles
R= Constant
As any amount gas is neither added nor released out, we can take 'n' as a constant.
So, we can conclude P is directly proportional to T when V is constant. Therefore, if Temperature increases, Pressure increases.
We can also conclude P is inversely proportional to V when T is constant. Therefore, if Volume decreases, Pressure increases.
Though the equation above is strictly for the ideal gases, the conclusions are applicable for all the fluids.
If we consider a cylinder-piston scenario, we can increase the pressure by adding extra weight to the piston.
