Question

Problems 2 and three pls with reasoning ! Thanks

2) A sample of gas is in a cylinder with a moveable piston. The (m force on the piston can be varied, altering the pressure and 6 volume. A sample of gas is taken from an initial state to a final state following a curve on a pV diagram at right. The final temperature is n 002 mo End Start a. higher than the initial temperature. b. the same as the initial temperature G lower than the initial temperature. 100 300 A sample of gas is in a cylinder with a moveable piston.

Answer 1

Ideal gas p_1 v_1 = n RT_1 p_2 v_1 = nRT_2 p_1v_1/p_2 v_2 = T_1/T_2 T_2 = T_1 p_2 v_2/p_1 v_1 T_2 = T_1 P_2 V_2/p_1 v_1 T_2 = T_1 v_2/v_1 as v_2 < v_1 so T_2 < T_1 (v_2 = 100 v_1 = 200) so lower than initial temperature option c from the graph it self it is obvious that the process will be isothermal In isothermal process initial temperature will be equal to find temperature
