Question

what happens to the volume of a gas when its temperature increases (according to charles law)?
volume doubles
volume becomes negative
volume decreases
volume increases
volume remains the same

Explanation:

Charles' Law states that for a given amount of gas at constant pressure, the volume \(V\) is directly proportional to the absolute temperature \(T\) (\(V = kT\), where \(k\) is a constant). When temperature \(T\) increases, since \(V\) and \(T\) are directly proportional, the volume \(V\) of the gas must also increase. Volume cannot double unless temperature doubles (not stated in the general question about temperature increase). Volume cannot be negative (physical quantity of volume for gas is non - negative). Volume does not decrease as it is directly proportional to temperature. And volume does not remain the same as there is a change in temperature.

Answer:

Volume increases
