Zander is conducting an investigation, and he used this video. Which statement best describes what Zander is testing in his experiment?   When a substance changes from a gas into a liquid due to a change in temperature, melting occurs, which is a physical change. When a substance changes from a solid into a liquid due to an increase in temperature, it is a physical change. When a substance changes from a gas into a liquid due to a decrease in temperature, the substance cools down and condenses, which is a phase change. When a substance changes from a liquid into a gas due to a decrease in temperature, the substance evaporates and cools down, which is a phase change.

i can ! i just need to know what the paragraph is! : p

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
