Consider the graph. A graph labeled Heating Curve has time as the horizontal axis and Temperature as the vertical axis. A line starts at 0 and rises to 1500 degrees where it levels off briefly; this section of line is labeled solid. The line continues to rise until it levels off at about 2750; this curve is labeled Liquid. After running horizontal for some time, the line rises again; this curve is labeled Gas. Based on the information in the graph, which statement best applies to a gas? Its particles have the highest average kinetic energy. Its particles have the smallest volume of all three states of matter. Its particles are slowing down because of a temperature increase. Its particles are moving apart due to repulsion between them.

Its particles have the highest average kinetic energy

Explanation:

This can be explained by the Kinetic Molecular Theory which explains the physical characteristics of solid, liquid, gas and how phases change from one to another.

The theory states the that average kinetic energy of particles is directly proportional to the temperature. When a solid is heated, its temperature and kinetic energy increase, eventually melting it into a liquid. If the temperature is raised even more, kinetic energy will increase even more and the liquid will eventually become a gas. This show that the gas has the highest temperature and hence the highest average kinetic energy compared to solid and liquid.
