Question

A)

A 41 g ice cube at −21◦C is dropped into a container of water at 0◦ C.

How much water freezes onto the ice? The specific heat of ice is 0.5 cal/g ·◦ C and its heat of fusion of is 80 cal/g.

Answer in units of g.

B)

A 0.0602 kg ingot of metal is heated to 205◦C and then is dropped into a beaker containing 0.411 kg of water initially at 18◦C.

If the final equilibrium state of the mixed system is 20.4◦C, find the specific heat of the metal. The specific heat of water is 4186 J/kg ·◦ C.

Answer in units of J/kg ·◦ C.
