Question

How much work to be done in decreasing the volume of an ideal gas by an amount of $2.4\times {10}^{-4}{m}^3$ at normal temperature and constant normal pressure of $1\times {10}^{5}N/m^2$ ?

• A. 28 joule
• B. 27 joule
• C. 25 joule
• D. 24 joule

Answer 1

The correct option is D

24 joule

$W=P△V=2.4\times {10}^{-4}\times 1\times {10}^5=24J$
