Question

A sample of nitrogen of mass 3.12g at 23.0°C is allowed to expand reversibly and adiabatically from 400cm3 to 2.00dm3. What is the work done by the gas?​

Answer 1

Answer:

1. nitrogen is not type of mass coz of whrenen

Answer 2

The sample of nitrogen of mass the work done by the gas in the $396.15K$.

Explanation:

In this exercise we have a sample of nitrone gas $m=3.12g$ at $23^{0}$$C$ that is allowed to expand reversibly and adiabatically from $0.400dm^{3}$ to $2.0dm^{3}$

we have to answer what is the work done by the gas

for $N_{2}$ gas known values are,

$m=3.12g$

$V_{i}=0.400dm^{3}$

$v_{f}=2.00dm^{3}$

Firstly we will convert value of initial temperature into ,

$T_{i}=23^{0}C$

$=(23+273.15)K$

$=396.15K$.
