Enter your answer in the provided box.

A 43.1−L volume of methane gas is heated from 24°C to 78°C at constant pressure. What is the final volume of the gas?

Answer 1

V₂ = 50.93 L

Step-by-step explanation:

Initial volume,
`V_1=43.1\ L`

Initial temperature,
`T_1=24^(\circ) C=24+273=297\ K`

Final temperature,
`T_2=78^(\circ) C=78+273=351\ K`

We need to find the final volume of the gas. The relation between the volume and the temperature is given by :

`(V_1)/(T_1)=(V_2)/(T_2)\\\\V_2=(V_1T_2)/(T_1)\\\\V_2=(43.1* 351)/(297)\\\\V_2=50.93\ L`

So, the final volume of the gas is 50.93 L.
