ACCORDING TO CHARLES’ LAW, THE VOLUME OF A GAS BECOMES ZERO AT

• A. 0°C
• B. -100°C
• C. -273°C ✓
• D. -373°C

Charles’ law states that the volume of a gas is directly proportional to its absolute temperature, provided that the pressure remains constant. Absolute temperature is measured in Kelvin (K), which is based on a thermodynamic scale where 0°C equals 273.15 K. Therefore, according to Charles’ law, the volume of a gas would approach zero when its absolute temperature reaches 0 Kelvin (negative 273.15 degrees Celsius). This temperature is known as absolute zero and represents the lowest possible temperature theoretically achievable. It’s important to note that reaching this temperature in real-world conditions is impossible with current technology or natural processes.

In other words, according to Charles’ law, the volume of a gas becomes zero at -273°C, which is also known as absolute zero. This temperature is the point at which all molecular motion ceases, and gases theoretically occupy no volume.

Charles’ law states that the volume of a given mass of gas is directly proportional to its absolute temperature, provided that pressure remains constant. In other words, as the temperature of a gas decreases, its volume also decreases proportionally until it reaches absolute zero.

At -273°C (0 Kelvin), the gas molecules have minimal kinetic energy and are essentially at rest. This results in the complete collapse of the gas into a theoretical point with zero volume.
