Explanation:
ozone is a type of oxygen. It's chemical compound is 03. Just 1 more molecule than regualr oxygen.
Glad I was able to help!!
The temperature increase when energy in is greater than energy out, and temperature decreases when energy out is than energy in.
Answer:
4 elements for C7H5(NO2)3
A pure liquid has a constant boiling point (at constant pressure). A change in boiling during distillation is an indication of impurity. The opposite, proposition, however, is not always true, and a constant boiling point does not necessarily mean that the liquid is pure.
This is because, at the boiling point, vapor and liquid are in equilibrium, and, if the composition of the vapor and liquid remains constant through the process, the temperature will also remain constant.
The boiling point can differ by location depending on pressure. Why does not a pure liquid in a distilling flask vaporize all at once whilst the boiling temperature is reached? Additional heat must be supplied for a phase change to occur.

Explanation -
<em>First: Ice will not evaporate in boiling water, it will melt. The input of energy is required to overcome the attractive forces between water molecules at the boiling point). This is in excess of the heat energy needed to raise water tothe temperature of the boiling point.</em>
