OP warned about not using the homework template
An ideal gas is compressed from a volume of Vi = 4.50 L to a volume of Vf = 3.00 L while in thermal contact with a heat reservoir at T = 295 K as in the figure below. During the compression process, the piston moves down a distance of d = 0.120 m under the action of an average external force of F = 21.0 kN.
(a) Find the work done on the gas, I Solved That its 2.5KJ.
ideal gas is PV = nRt
work done is W = F(yf - yi)
so work is W = 21000N*(.120m)
W = 2520J or 2.5 KJ(b) Find the change in internal energy of the gas.
(c) Find the thermal energy exchanged between the gas and the reservoir.
i tried to solve b and c but with no pressure or moles i have no formula that can get me the change in internal energy.
for b the change is internal energy is given by: U = Q + W
i have the W as 2.5kJ but i am still Missing Q the energy transferred to the Gas by Heat
