Final answer:
Doubling the temperature of a gas at constant volume will double the pressure, in accordance with Gay-Lussac's law.
Step-by-step explanation:
When the temperature of a fixed amount of gas is doubled at constant volume, the pressure will double as well. This is because, according to Gay-Lussac's law, for a given amount of gas held at constant volume, the pressure is proportional to the absolute temperature. Therefore, if the temperature doubles, the pressure will also double.
If the temperature of a fixed amount of a gas is doubled at constant volume, the pressure of the gas also doubles. This is a direct application of Gay-Lussac's law, which states that for a given amount of gas at constant volume, the pressure is proportional to its absolute temperature. Therefore, if temperature is doubled, the pressure is also doubled, answering option a.
