How do molecules at warm temperatures differ from molecules at cool temperatures?

• At warm temperatures, molecules move around more.

• At warm temperatures, molecules grow in size.

• At warm temperatures, molecules exchange electrons more easily.

• At warm temperatures, molecules combine with each other more easily.
