1. How much work is done on the gas in each of the following processes? C. a. piPa 3000 2000 1000 p(Pa) 3000 2000 1000 V(m V(m' w= W= W= 2. Do each of the following describe a property of a system, an interaction of a system with its environment, or both? Explain. A) Temperature B) Heat C) Thermal Energy

Answer 1

a) given p-v diagram can be drawn as follows rightarrow v(m^3) Here words done, w = -infinity^2_1 P dv = -p integral^2_1 1. Dv = -p (v_2 - v_1) = -2000 times (3 - 0) = -200 times 3 w = -6000 pa - m^3 b) given p - v diagram can be drawn as also of trapezium is given by A = 1/2 (BC + AD) times CD A = 1/2 (3000 + 1000) (3 - 1) \r\n A = 1/2 times 4000 times 2 A = 4000 pa - m^3 a) given p-v diagram can be drawn as follows Hire work done W = Area of two trapezium \r\n i.e, w = 2 times Area of ABCD w = 2 times 1/2 (3000 + 2000) times (3 - 2) = 5000 times 1 w = 5000 pa - m^3 \r\n solution a) Temperature is also as property of system which is related to thermal energy whereas temperature difference will be interaction of system with its
