What is the critical point of a substance?

The temperature at which a substance can exist as a solid
The temperature and pressure at which gas and liquid phases are indistinguishable
The point at which a substance boils
The temperature at which a substance freezes

What is the critical point of a substance?

Step 1: Understand that substances can exist in different states, like solid, liquid, and gas.
Step 2: Know that the critical point is a special condition for a substance.
Step 3: Learn that at the critical point, the temperature and pressure are very high.
Step 4: Realize that at this point, the gas and liquid forms of the substance cannot be told apart.
Step 5: Remember that beyond the critical point, the substance is in a supercritical state, which has properties of both gas and liquid.
