H2O Unit - Chemistry

Define specific heat capacity

The amount of energy required to raise the temperature (usually 1 degrees C) of a set amount of substance (usually 1 g).

Does water have a high or low specific heat capacity? How does the demonstration show this?

High. It required more heat energy (had to absorb heat energy for longer) to bring the same volume to the same temperature.

Explain why water has a relatively high specific heat capacity.

A relatively large amount of energy is absorbed to break or loosen hydrogen bonds between water molecules.
