Question

at a constant pressure, the volume of a gas doubles when the temperature in kelvins doubles. this is a statement of which gas law?
boyles law
charless law
gay - lussacs law
combined gas law

Explanation:

Charles's law states that at constant pressure, the volume of a given mass of gas is directly proportional to its absolute temperature (in Kelvins). When the temperature doubles, the volume doubles under constant - pressure conditions. Boyle's law is about pressure - volume relationship at constant temperature, Gay - Lussac's law is about pressure - temperature relationship at constant volume, and the combined gas law combines pressure, volume, and temperature relationships.

Answer:

B. Charles's law
