Question

what is the state of matter at it's critical temperature?​

Answer 1

Answer:

phase changes

The normal boiling point is… …a specific temperature called the critical temperature, which is different for each gas, no phase change occurs, and the resulting substance is a gas that is just as dense as a liquid.

Answer 2

Answer:

${\tt{{\underline{\underline{\huge{Critical \: Temperature :}}}}}}$

• The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied.

• Every substance has a critical temperature.

• Gases can be converted to liquids by compressing the gas at a suitable temperature.

• Gases become more difficult to liquefy as the temperature increases because the kinetic energies of the particles that make up the gas also increase.
