Answer: 0.0022m3
Explanation:
Initial volume of mercury V1 = 0.002m3 (note that the unit of volume can be cm3, m3, dm3 or liters)
Initial temperature T1 = 20°C
Convert temperature in Celsius to Kelvin
( 20°C + 273°C = 293K)
Final temperature T2 = 50°C
( 50°C + 273°C = 323K)
Final volume V2 = ?
According to Charle's law, the volume of a fixed mass of a gas is directly proportional to the temperature.
Mathematically, Charles' Law is expressed as: V1/T1 = V2/T2
0.002/293 = V2/323
To get the value of V2, cross multiply
V2 = (323 x 0.002) / 293
V2 = 0.646 / 293
V2 = 0.0022 m3
Thus, the new volume of mercury will be 0.0022m3
