# How does the pressure of a gas change when it is heated and compressed?

According to the Mendeleev-Clapeyron equation:
pV = (m / M) * R * T, where p is the gas pressure, V is the gas volume, m is the gas mass, M is the molar mass of the gas, R is the universal gas constant 8.31 J / (mol * K), T is the gas temperature.
Let’s move the volume to the right side:
p = ((m / M) * R * T) / V.
As the temperature rises, as can be seen from the formula, the pressure will increase, since it directly depends on the temperature.
When the gas is compressed, its volume decreases, and therefore, since we have an inverse relationship, the pressure also increases.
Answer: The pressure rises with both heating and compression.
