Question: The law that relates the volume of a gas to its temperature at constant pressure is known as: (2018)

Options:

Correct Answer: Charles\'s Law

Exam Year: 2018

Solution:

Charles\'s Law states that the volume of a gas is directly proportional to its absolute temperature at constant pressure.

The law that relates the volume of a gas to its temperature at constant pressure is known as: (2018)

The law that relates the volume of a gas to its temperature at constant pressure is known as: (2018)

Step 1: Understand that gases can change volume when their temperature changes.
Step 2: Remember that this relationship happens at constant pressure, meaning the pressure of the gas does not change.
Step 3: Learn that Charles's Law describes this relationship.
Step 4: Know that Charles's Law states that as the temperature of a gas increases, its volume also increases, and vice versa.
Step 5: Recognize that the temperature must be measured in absolute terms (Kelvin) for the law to apply correctly.

Charles's Law – Charles's Law states that the volume of a gas is directly proportional to its absolute temperature when pressure is held constant.
