Question

matter can go through phase changes due to a change in either of these two conditions. choose both. (hint: think about your online lab.) a. pressure b. temperature c. color d. metal

Explanation:

Phase changes of matter are physical changes. Temperature changes can cause substances to change between solid, liquid, and gas states (e.g., ice (solid) melts to water (liquid) when heated - temperature change). Pressure changes can also affect phase changes. For example, at lower pressures, the boiling point of a liquid is lower. Color and being a metal are not factors that directly cause phase changes of matter.

Answer:

A. pressure, B. temperature
