Question

In a related practical activity, 2 litres of a gas were heated from 35 °C to 75 °C. If the pressure was kept constant, calculate the final volume of the gas.​

Answer 1

2.26l

Step-by-step explanation:

From the general gas equation:

P1V1/T1 = P2V2/T2

Since pressure remained constant we can say:

V1/T1 = V2/T2

so to convert to kelvin add 273 to both temperature values then we can say:

1 m^3= 1000 L

2l=0.002m^3

Then;

0.002/308=V/348

V=(0.002/308)348

Final volume=0.002259m^3

=2.6l(1 decimal place)
