A 20 gram piece of metal is added to a sample of 100 grams of water inside a calorimeter. If the metal is at a temperature of 125° Celsius and the water is at 20° Celsius, which of the following best describes what will occur inside the calorimeter?

The final temperature of the water will be 105° Celsius.

The energy lost by the metal equals the energy gained by the water.

The final temperature of the water will be lower than the initial temperature.

The temperature gained by the water will equal the temperature lost by the metal.
