Two objects, A and B, are brought into contact with each other. The initial temperature of object A is 230 K. The heat capacity of object A is a constant 3 J/K and the heat capacity of object B is a constant 4 J/K. Through the exchange of heat the two objects eventually obtain a common nal temperature of 320 K.

1)The initial temperature of object B was ____ K.

2) The amount of heat exchanged during the process of obtaining the final temperature was ______J.

3) The final temperature would be (higher, lower, stay the same), if the heat capacity of object B was higher and the other given parameters remain constant. _______

Three objects (A, B, and C) are originally far apart. Object B is brought into contact with object A, and no heat flows from one object to the other. Then, object B is moved away from object A and brought into contact with object C. When object B touches object C, the temperature of the two objects changes. Objects B and C eventually reach thermal equilibrium. (a) Give as much information as you can about the original temperatures of the...
