उत्तर

Given:

T1 = Initial temperature = 0°C = 0 + 273.15 = 273.15 K,
V1 = Initial volume = 2 dm3
T2 = Final temperature = 273.15 K + 10 = 283.15 K

To find: V2 = Final volume

Formula: `"V"_1/"T"_1="V"_2/"T"_2` (at constant n and P)

Calculation:

According to Charles’ law,

`"V"_1/"T"_1="V"_2/"T"_2` (at constant n and P)

∴ V2 = `("V"_1"T"_2)/"T"_1=(2xx283.15)/273.15` = 2.073 dm3

The new volume of a given mass of gas is 2.073 dm3
