What state(s) of matter has/have a definite volume?

• Solid

• Liquid

• Gas

• Plasma

Answer explanation

Both solid and liquid states of matter have a definite volume. They maintain their shape and occupy a fixed amount of space.

What state(s) of matter do(es) not have a specific shape?

• Solid

• Liquid

• Gas

• Plasma

What is a SI unit for pressure?

• Kelvin

• Pascal

• Newton

• Liter

If we have a 10mL sample of a gas at 200 hPa and then increase the volume until it equals 500mL, what would be the new pressure of the gas in Pa?
