A 65 g ice cube at 0 °C is placed in an insulated box that contains 8 g of steam at 200 °C. What is the equilibrium temperature reached by this closed system? Approximate the specific heat capacity of steam to be 1.5 J/g oC. All the other values can be found on the textbook. [Note: Assume that all of the steam condenses.]

A 50·g ice cube (at 0°C) is placed in an insulated cup with 250·g of water which is at 46°C. The latent heat of fusion for ice is 80·cal/g and the specific heat of water is 1.0·cal/g/°C. (a) How much heat will the ice have to absorb from the water to completely melt (and turn into 0°C water)? ___ cal. (b) Find the temperature of the 250·g of water initially at 46°C after it loses the heat required to melt...

1) An ice cube of mass m at 0 ?C is placed in a large 20 ?C room. Heat flows (from the room to the ice cube) such that the ice cube melts and the liquid water warms to 20 ?C. The room is so large that its temperature remains nearly 20 ?C at all times. Calculate the change in entropy for the (water + room) system due to this process. Assume that m is in kg. 2) A mass...
