Question

A 49.7 mL sample of gas in the cylinder is warm from 20°C to 92°C. What is the volume of the final temperature

Answer 1

61.9mL

Step-by-step explanation:

Given parameters:

Initial volume = 49.7mL

Initial temperature = 20°C = 293K

Final temperature = 92°C = 365K

Unknown:

Final volume = ?

Solution:

To solve this problem, we simply apply the Charles's law which states that "the volume of a fixed mass of a gas varies directly as it absolute temperature if the pressure is constant";

`(V1)/(T1) = (V2)/(T2)`

V and T are volume and temperature values

1 and 2 are initial and final states

Now insert the parameters and solve;

`(49.7)/(293)` =
`(V2)/(365)`

V2 = 61.9mL
