Chemistry 2004 JAMB Past Questions - Question 5: According to Charles' law, the volume of a gas becomes zero at

Correct Answer

C

Explanation

Charles's Law describes the relationship between the volume and temperature of a gas, assuming pressure and the amount of gas remain constant. It states that the volume of a gas is directly proportional to its absolute temperature.

The law is often expressed mathematically as:

\[ V \propto T \]

where:
- \( V \) is the volume of the gas,
- \( T \) is the absolute temperature.

According to Charles's Law, as the temperature of a gas decreases, its volume should also decrease, approaching zero at absolute zero temperature. Absolute zero is the lowest possible temperature, at which the fundamental particles of nature have minimal vibrational motion. It is equivalent to 0 Kelvin or -273.15 degrees Celsius.

In practice, achieving absolute zero is not possible, but Charles's Law suggests that as you approach absolute zero, the volume of a gas will approach zero as well.
According to Charles' law, the volume of a gas becomes zero at a temperature of -273.15 degrees Celsius, which is also known as absolute zero. At this temperature, the particles of the gas would theoretically cease all motion.
