Questions: A sample of gas at a constant pressure is heated. What will happen to its volume? remain the same increase temperature change has no effect on a gas not enough information is given decrease

Solution Steps

According to Charles's Law, for a given amount of gas at constant pressure, the volume of the gas is directly proportional to its absolute temperature (measured in Kelvin). Mathematically, this can be expressed as:

\[ V \propto T \]

or

\[ \frac{V_1}{T_1} = \frac{V_2}{T_2} \]

where \( V \) is the volume and \( T \) is the temperature.

Given that the pressure is constant and the gas is heated, the temperature \( T \) increases. According to Charles's Law, if the temperature increases, the volume \( V \) must also increase to maintain the proportionality.
