Six objects are placed in a 500∘F (260∘C) oven and allowed to reach thermal equilibrium. Each object has a mass of 1. 0 kg. The specific heat and thermal conductivity of each substance are denoted by c and k.

a) Rank these objects on the basis of their temperatures when removed from the oven.

b) When removing the objects from the oven, you accidentally touch each one with your hand. Rank these objects on the basis of how hot they feel.

c) Each of the objects is immediately dunked in an identical tub of cold water. The tubs are quickly sealed and insulated. Rank the objects on the basis of their temperature on reaching equilibrium with the water.
