A sample of a gas occupies 5.25 m^3 at an absolute pressure of 1.00atm & temp of 20 degrees C:
a) what is the volume if the pressure is 1.00 atm but the temp is raised to 75 degrees C.
b) calculate the pressure in the gas sample if the volume is held at 5.25 m^3 while the temp is lowered to negative 40 degrees C.
