Questions & Step-by-Step Solutions
What is the critical temperature of a substance?
Correct Answer: Critical temperature is the maximum temperature at which a gas can be converted into a liquid.
Step 1: Understand that substances can exist in different states, like solid, liquid, and gas.
Step 2: Know that gases can be turned into liquids by applying pressure and lowering temperature.
Step 3: Learn that each substance has a specific temperature called the critical temperature.
Step 4: Recognize that if the temperature of a gas is above its critical temperature, no matter how much pressure is applied, it will not turn into a liquid.
Step 5: Conclude that the critical temperature is the highest temperature at which a gas can be converted into a liquid.
