Question

The state or phase of a given set of matter can change depending on _____________.

• A. temperature
• B. pressure
• C. Both a and b
• D. None of above

Answer 1

Answer: (C)

Both a and b

The state or phase of a given set of matter can change depending on pressure and temperature conditions, transitioning to other phases as these conditions change to favor their existence; for example, solid transitions to liquid with an increase in temperature. When pressure increases on a substance in a gas phase it can cause the substance to be condensed or a decrease in pressure on the substance can cause it to vaporize.

Hence, option $C$ is correct.
