Hot and cold water are mixed. 50 calories are transferred from the hot water. How many calories will transfer to the cold water? How do you know?

• 100 calories, since double the amount transfers to the cold water.

• 50 calories will transfer to the cold water, since 50 calories transferred away from the hot water.

• The energy transfer will get lost to the outside atmosphere, so no calories will transfer to the cold water.

• There is not enough information.

• conduction

• radiation

• connection

A thermometer is not used to measure heat because

• heat measures the average kinetic energy of particles.

• a thermometer measures heat.

• heat is measured in calories, the amount necessary to raise the temperature of 1g of water 1^oC.

• wait, a thermometer does measure heat!
