A fixed amount of ideal gas is held in a rigid container that expands negligibly when heated at 20 •C the gas pressure is P. If we add enough heat to increase the T from 20•C to 40•C, the pressure will be A) impossible to determine since we do not know the number of moles of gas in the container. B) greater than 2P C) less than 2P D) equal to 2P E) impossible to determine since we do not know the volume of gas in the container

Solution

Answer is Option C

C) less than 2P

pV = nRT

P1/T1 = P2/T2

P2 = P1*T2/T1

double the absolute temperature of the gas and convert the two temperatures

by doubling celsius 2K = 2*273 = 546
