Question

A sample of a gas in a balloon has a volume of 2.22 L and temperature of 23.9 °C. Calculate the volume when the temperature is raised to 46.1°C at constant pressure.

Answer 1

Answer:

Volume = 4.28L

Explanation:

Charles's gas law relates the volume and temperature of a gas at constant pressure. This law says that at constant pressures if we raise the temperature of a gas it will expand and if we reduce the temperature the volume will decrease. The formula is as follows:

${\displaystyle {\frac {V_{1}}{T_{1}}}={\frac {V_{2}}{T_{2}}}}$

So, the initial conditions are 2.22L and 23.9 °C ant the final conditions are 46.1 °C we replace them in the equation. And then we solve it.

${\displaystyle {\frac {2.22}{23.9}}={\frac {V_{2}}{46.1}}$

${\displaystyle {\frac {2.22}{23.9}} {46.1}={V_{2}$

${\displaystyle {4.28}={V_{2}$
