Question

A gas-forming reaction produces 1.15 m 3 of gas against a constant pressure of 102.0 kPa. Calculate the work done by the gas in joules.

Answer 1

Answer:

The work done by the gas is 117,300 Joules.

Explanation:

Pressure applied on the gas , P= 102.0 kPa = 102000 Pa ( 1kPa = 1000 Pa

Change in volume of the gas ,ΔV= $1.15 m^3$

Here the work is done by system so, the value of work done will be negative.

$W=-P\Delta V$

$=W=-102000 Pa\times 1.15 m^3=117,300 J$

The work done by the gas is 117,300 Joules.
