which statement best describes gay-lussac’s law?\npressure is inversely proportional to volume.\npressure is…

Brief Explanations:

Gay - Lussac’s law states that for a given mass of a gas at constant volume, the pressure of the gas is directly proportional to its absolute temperature. Let's analyze each option:

• The first option ("Pressure is inversely proportional to volume") describes Boyle's law (for constant temperature).
• The second option ("Pressure is inversely proportional to temperature") is incorrect as per Gay - Lussac’s law.
• The third option ("Pressure is directly proportional to volume") is incorrect and does not match any gas law in the standard form.
• The fourth option ("Pressure is directly proportional to temperature") matches the statement of Gay - Lussac’s law (when volume is constant).

Answer:

The option: Pressure is directly proportional to temperature
