26. A reaction that absorbs heat from its surroundings is called ______________.
27. The metric unit typically used to measure temperature in this unit.

1. The heat released by a system is equal to the heat ______ by its surroundings.
3. Between wood (Cp = 2.03) and aluminum (Cp = 0.92), the material that heats up faster in the sun.
5. The amount of energy transferred to or from a substance when changing temperatures.
7. An insulated device used to measure the absorption or release of heat in a chemical or physical process.
9. In the calorimetry equation -q(sys) = q(surr), the negative sign indicates that energy is being ______.
10. The specific part of the universe being studied in a reaction, usually the chemicals themselves.
13. The science of measuring the heat flow into or out of a system for chemical and physical processes.
14. To ensure the temperature is uniform throughout the water in a calorimeter, you must do this to the mixture.
16. In an endothermic chemical equation, "Heat" or amount of kJ is written on this side of the arrow.
17. In a calorimetry experiment, the "system" is typically the ______, while the water is the "surroundings".
