Chemical energy is energy stored in the bonds of chemical compounds, like atoms and molecules. This energy is released when a chemical reaction takes place.
The statement that describes the energy changes associated with evaporation and boiling is that atoms gain energy during evaporation and boiling.
<h3>What is evaporation?</h3>
Evaporation is defined as process by which a solution changes from its liquid state to gaseous state.
Boiling is defined as the heating of water to a point that the vapor pressure is equal to the pressure of the gas above it.
In both phase transition stages, the molecules gain enough energy to change its state to another state.

<span>From his observations of cannon drilling, Count Rumford concluded that heat could NOT be a form of C. matter.
Although all matter contains heat energy, heat itself is not a form of matter, but just one of its integral parts.

Voltage = 1.5V
Resistance = 1.5 ohm
Current = V/R = 1.5/1.5 = 1A
