Answer the following question given this paragraph: Heat expansion is a result of the increase of kinetic energy of the molecules. As their movement increases, they bump into each other more and the material slightly expands as a result. Most materials expand with heat. Water is a particularly interesting substance in that it contracts as its temperature increases from to (and then expands from to ). Q: Heat expansion is a result of the increase of what type of energy, exhibited by molecules bumping together? Choices: - light energy - radioactivity - harmonic energy - kinetic energy A:
kinetic energy

Answer the following question given this paragraph: A storm is an episode of severe weather caused by a major disturbance in the atmosphere. Storms can vary a lot in the time they last and in how severe they are. A storm may last for less than an hour or for more than a week. It may affect just a few square kilometers or thousands. Some storms are harmless and some are disastrous. The size and strength of a storm depends on the amount of energy in the atmosphere. Greater differences in temperature and air pressure produce stronger storms. Types of storms include thunderstorms, tornadoes, hurricanes, and winter storms such as blizzards. Q: A winter storm is called what? Choices: - snow storm - tempest - gale - blizzard A:
**Answer**
blizzard
