Lab: Thermal Energy Transfer Answers

When using a calorimeter, the initial temperature of a metal is 70.4C. The initial temperature of the water is 23.6C. At the end of the experiment, the final equilibrium temperature of the water is 29.8C.

The unit often used in chemistry and physics to measure energy, such as for work or electrical current, is the [___]. We can also use this unit, as we did in this lab, for measuring [___]. This is a property that is quantified by the energy needed per [___] of material to raise the temperature by one [___]. The unit for this measure is therefore [___].
