Question

If you have a gas at 0 degree Celsius and 365mL, what would the volume be if the temperature rises to 25 degree Celsius if the pressure remains constant?

Answer 1

In this case, we have a gas at constant pressure that varies its volume and temperature. The law that we can apply in this case is Charles's law, which relates temperature and volume while maintaining a constant pressure. Charles's law is described as:

`(V_1)/(T_1)=(V_2)/(T_2)`

Where,

V1 is the initial volume in liters, V1=365mL=0.365L

T1 is the initial temperature in Kelvin, T1=0°C=273.15K

T2 is the final volume in Kelvin, T2=25°C=298.15K

V2 is the final volume in Liters, V2=?

Now, we clear V2 and we replace the known data:

`\begin{gathered} V_2=(V_1)/(T_1)* T_2 \\ V_2=(0.365L)/(273.15K)*298.15K=0.398L*(1000mL)/(1L) \\ V_2=398mL \end{gathered}`

Answer: If the temperature rises to 25 degree Celsius the volume would be 398mL
