Answer:
38.1 L
Step-by-step explanation:
Data given:
initial volume V1 of a gas = 3 L
initial Temperature T1 of a gas = 21 °C
convert Temperature to Kelvin
T1 = °C +273
T1 = 21°C + 273 = 294 K
final Temperature T2 of a gas = 100°C
convert Temperature to Kelvin
T2 = °C +273
T2 = 100°C + 273 = 373 K
final Volume V2 of a gas = ?
Solution:
This problem will be solved by using Charles' law equation at constant pressure.
The formula used
V1 / T1 = V2 / T2
As we have to find out Volume, so rearrange the above equation
V2 = V1 x T2 / T1
Put value from the data given
V2 = 3 L x 373 K / 294 K
V2 = 38.1 L
So the final Volume of a gas = 38.1 L
