Temperature is a measure of the average energy consumption r motion of an objects particles. Sometimes if enough heat is added to or removed from an object, it can change its state. Which of the following can occur if the temperature decreases in a system? A) a solid becomes a liquid B) a liquid becomes a gas C) a solid becomes a gas D) a liquid becomes a solid

If bacteria are much too small to see, what is one reason why can we see colonies in the petri dishes that have plenty of food to eat after only a few days?

How do water’s relative densities as a solid and a liquid differ from that of most other substances? water’s solid and liquid forms have different densities, while most other substances have solid and liquid forms with similar densities. water’s solid and liquid forms have similar densities, while most other substances have solid and liquid forms with different densities. water’s liquid form is less dense than its solid form, while the opposite is true of most other substances. water’s solid form is less dense than its liquid form, while the opposite is true of most other substances.
