Question

the substances shown are ordered (from left to right) in order of increasing
a density.
b kinetic energy.
c potential energy.
d intermolecular attractions.

Explanation:

Ice is a solid, water is a liquid and steam is a gas. As we go from solid - liquid - gas, the temperature increases. Temperature is a measure of the average kinetic energy of the particles. So, the kinetic energy of the particles increases from ice to water to steam. Density of ice is less than water, potential energy is related to position and intermolecular attractions decrease from solid to gas.

Answer:

B. kinetic energy
