How much energy was lost by the water in the cup assuming that 4.19 Joules of energy are required to change the temperature of 1 gram of water by 1 degree Celsius?
How much energy was gained by the snow?
How much of the snow's energy gain was required to increase its temperature after melting (snow becomes water at temperatures over 0 Celsius)?
Assuming that the snow started at 0 Celsius, how much energy per gram was required to melt it at that temperature?
Sketch temperature vs. time graph and use this graph to estimate how much thermal energy was exchanged between the system and the room during the melting process.
