Reflecting on Gas Volume and Temperature Relationship

How does temperature affect the volume of gas?

In what way does the volume of gas change as temperature increases or decreases?

Answer:

The volume of gas is directly proportional to its temperature. As the temperature increases, the volume of gas also increases, and conversely, as the temperature decreases, the volume of gas decreases.

Gas volume and temperature have a direct relationship due to the behavior of gas molecules. According to Charles's Law, at constant pressure, the volume of a gas is directly proportional to its absolute temperature. This means that as the temperature increases, the gas molecules gain kinetic energy and move faster, leading to an increase in volume. On the other hand, when the temperature decreases, the gas molecules lose energy and move slower, resulting in a decrease in volume.

For example, in the given data where the volume of gas is 693 mL at 45°C, if the temperature is increased to 150°C, the volume of gas would be 922 mL. This demonstrates how temperature directly influences the volume of gas.
