# At standard temperature a gas has a volume of 275 mL. If the temperature is increased to 130°C, but the pressure is held constant, what is the new volume?

Well, old Charles' Law holds that $V \propto T$ at constant pressure......for a given quantity of gas.....
So if $V \propto T$, then $V = k T$; if we solve for $k$ under different conditions of volume and temperature.....
${V}_{1} / {T}_{1} = {V}_{2} / {T}_{2}$, temperature is measured in $\text{degrees Kelvin}$.
And V_2=V_1/T_1xxT_2=(275*mL)/(298*K)xx403*K=??mL
