Specific Heat Problems Q = mCpT Units are Joules (J)

1. How much heat is needed to raise the temperature of 400 grams of water from 0.0 C
to 15 C the Specific Heat of water is 4.186 J/gC?
A(Asking) – Q =?
G(Giiven) – m=400g, Cp = 4.186 J/g C, T = 15.0 C- 0.0 C =15 C
E(Equation) – Q= mCpT
S(Substitute & Solve) – Q = (400 g)(4.186 J)(15 C) =

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
