First, restating the situation helps clarify what happens between states 1 and 2 on a pV diagram. In an ideal gas, the relation PV = nRT holds, with n and R constants for a given amount of gas.
Option: pressure
From a pV diagram perspective, a vertical move (state 1......Login to view full explanation登录即可查看完整答案

A thermally isolated system is made up of a hot piece of aluminum and a cold piece of copper; the aluminum and the copper are in thermal contact. The specific heat capacity of aluminum is more than double that of copper. Which object experiences the greater magnitude gain or loss of heat flow during the time the system takes to reach thermal equilibrium?
