A cylinder closed at both ends is separated into two equal parts (45 cm each) by a piston impermeable to heat. Both the parts contain the same masses of gas at a temperature of 300K and a pressure of 1 atm. How much the gas should be heated in one part of the cylinder toshift the piston by 5 cm and the pressure of the gas after shifting the piston
