Question

which conclusion can be made from gay - lussacs law? (1 point) at a constant temperature, the pressure of a gas is directly proportional to the volume. for a constant volume, the pressure of a gas is indirectly proportional to the temperature, in kelvin. for a constant volume, the pressure of a gas is directly proportional to the temperature, in kelvin. at a constant temperature, the pressure of a gas is indirectly proportional to the volume.

Explanation:

Gay - Lussac's law states that for a given mass of gas at constant volume, the pressure of the gas is directly proportional to its absolute temperature (in Kelvin). The first and fourth options describe Boyle's law (pressure and volume relationship at constant temperature). The second option has an incorrect relationship (it should be directly proportional, not indirectly).

Answer:

C. For a constant volume, the pressure of a gas is directly proportional to the temperature, in Kelvin.
