If the temperature increases in a sample of gas at constant volume, then its

a. volume increases
b. pressure decreases
c. pressure increases
d. volume decreases

Plz help me, I don't know it.

well it says , "constant volume" so that would rule out

a) and d)
So what does common sense tell you about the pressure , does it increase or decrease as the temperature goes up?

Thank you for your help, Reiny

To answer this question about the relationship between temperature and volume in a sample of gas at constant volume, we need to understand the concept of Charles's Law.

Charles's Law states that for a given amount of gas at constant pressure, the volume is directly proportional to the temperature. In simpler terms, as the temperature increases, the volume of the gas also increases, and as the temperature decreases, the volume of the gas decreases.

So, to find the correct answer to your question, we can conclude that if the temperature increases in a sample of gas at constant volume, then its volume also increases. Therefore, the correct answer is option (a) volume increases.

In summary:
- Charles's Law states that when the temperature of a gas at constant pressure increases, its volume also increases.
- Therefore, in this scenario, if the temperature increases in a sample of gas at constant volume, then the volume of the gas increases.
