Question:
40ml of a gas is collected at 25 degree Celsius.if the temperature is raised to 50degree Celcius and the pressure remains constant ,what would be the new volume of the gas
Answer:
Applying Charles law, V1/T1 = V2/T2 (at constant pressure)
Where,
T1 = 25 °C = 25 + 273 = 298 K
T2 = 50 °C = 50 + 273 = 323 K
V1 = 40 ml
V2 = ?
So, 40 /298 = V2 /323
V2 = 40 x 323/298 = 43.35
Hence, new volume of the gas is 43.35 ml.
