An ideal gas is placed in a tall cylindrical jar of crosssectional area 0.080m^2. A frictionless 0.10kg movable piston weight is supported by the gas pressure in the jar. When the gas is heated (at constant pressure) from 25C to 55C , the piston rises 1.0cm. How much heat was required for this process? Assume atmospheric pressure outside. A= 0.08m^2 , m=0.1kg, , Delta P= 0 --> Q= Delta U + W= Delta U + P(Delta V) Tl= 298K , Th= 328K , d=0.01m , Q=? I am unsure where to begin here.
