The gas pressure in the cylinder at 27 degrees Celsius is 240 kPa. What will be the pressure

The gas pressure in the cylinder at 27 degrees Celsius is 240 kPa. What will be the pressure after heating the gas to 100 C?

For a constant mass of gas at a constant volume, the relationship between pressure and temperature is given by the formula (Charles’s law):

P / T = const or P1 / T1 = P2 / T2 = …

We translate the values of temperatures in degrees Celsius into values on the Kelvin scale:

T1 = 27 + 273 = 300 K;

T2 = 300 K + 100 K = 400 K;

240 kPa / 300 K = P2 / 400 K;

P2 = (400 K * 240 kPa) / 300 K = 320 kPa.

Answer: 320 kPa.
