Ques1) Is it possible for two objects to be in thermal equilibrium if they are not in contact with each other? Explain.     Ques2) Explain why the thermal expansion of a spherical shell made of a homogeneous solid is equivalent to that of a solid sphere of the same material. A piece of copper is dropped into a beaker of water. If the water’s temperature increases, what happens to the temperature of the copper? Under what conditions are the water and copper in thermal equilibrium? Ques3)
