one mole of a monatomic gas expands from V_i = V_0 to V_f = 3V_0 according to the relationship:
p = P_0[1 - 0.9sin( (pi(V - V_0))/4V_0 )]
a) compute the work done by the gas as it expands from V_i = V_0 to V_f = 3V_0
b) compute the net heat flow during this expansion
c) does heat flow into or out of the gas during this expansion?
PV = nRT where P is pressure, V is volume, n is moles, R = 8.314 constant, T is temperature
Q = W = nRT ln (V_2/V_1) where W is work, Q is heat, V_2 and V_1 is volume
not sure what else
The Attempt at a Solution
I haven't got far because i don't understand the given relationship, what is the difference between the capital and lowercase p, is the lowercase p stand for momentum? i doubt it..
i used the second eq and tried to solve for work but didn't know how to implement the relationship given, where does it come into play?
any help appreciated...
