377 g of water at 81°C & 279 g of glycerin at 47°Care poured into a 427 g copper cup at 58°C. Assuming these threemake up a closed (or isolated) system, determine the FINALTEMPERATURE of the system.
A cube of ice is taken from the freezer at -9.4°C andplaced in a 100 g aluminum calorimeter filled with 278 g of waterat room temperature of 20°C. The final situation is observed to beall water at 15°C. What was the mass of the icecube?
274 g of water at 2°C is added to ice at 0°C. If thefinal temperature of the system (which you can assume is isolated)is 0°C, determine HOW MUCH ICE MELTED.
0.4 kg of steam at 100°C is added to 2.74 kg of ice at0°C. Determine the temperature of the mixture once thermalequilibrium is reached.
