Question

According to Gay-Lussac's law, when a fixed volume of gas increases in temperature, it must also?

1) decrease in pressure
2) increase in mass
3) increase in pressure
4) increase in volume

Answer 1

According to Gay-Lussac's law, when the temperature of a fixed volume of gas increases, the pressure of the gas also increases. Therefore, the correct answer is option 3) increase in pressure.

Step-by-step explanation:

According to Gay-Lussac's law, when a fixed volume of gas increases in temperature, it must also increase in pressure. According to Gay-Lussac's law, when the temperature of a fixed volume of gas increases, the pressure of the gas also increases.

This law states that for a given amount of gas held at a constant volume, the pressure is directly proportional to the absolute temperature.

As the temperature of the gas increases, the molecules move faster and collide with the walls of the container more frequently, resulting in an increase in pressure. Therefore, the correct answer is option 3) increase in pressure.
