Q5 (a) Object A and object 8 are at different initial temperatures when they are placed in a thermally insulated container and allowed to reach thermal equilibrium as shown in Figure 5. Object A has a mass of 7 kg: object B has a mass of 3 kg. Given the specific heat of object A is 500 in / kg .k. Determine the specific heat of object B, in /kg K.
