Darina [25.2K]

Explanation:

Given parameters:

Initial volume V1 = 200cm³

Initial temperature = 60°C

Final temperature = 120°C

Unknown:

Final volume = ?

Solution:

According to Charles law, at constant pressure, the volume of a given mass of gas is directly proportional to temperature.

mathematically;

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

1 and 2 are the initial and final states

V is the volume and T is the temperature

convert the temperature to kelvin

T1 = 60 + 273 = 333K

T2 = 120 + 273 = 393K

Input the parameters;

$\frac{200}{333} = \frac{V_{2} }{393}$

final volume is 236cm³
