The Pressure of a Sample of Gas Is Directly Proportional $50$

question 225

Essay

The pressure of a sample of gas is directly proportional to the temperature and inversely proportional to the volume.
(a) Write an equation that expresses this fact if $50$ L of gas exerts a pressure of $14$ kPa at a temperature of $350 ^ { \circ }$ K (absolute temperature measured on the Kelvin scale).
(b) If the temperature is increased to $400 ^ { \circ }$ K and the volume is decreased to $40$ L, what is the pressure of the gas?
