Question

The pressure P of a sample gas is directly proportional to the temperature T and inversely proportional to the volume V.

(a) Write an equation that expresses this variation. (Use k for the constant of proportionality.)

(b) Find the constant of proportionality if 100 L of gas exerts a pressure of 33.2 kPa at a temperature of 400 K (absolute temperature measured on the Kelvin scale).
k =

(c) If the temperature is increased to 500 K and the volume is decreased to 60 L, what is the pressure of the gas? (Round your answer to one decimal place.)
P = kPa
