When the ideal gas is compressed isothermally, then its pressure
When the ideal gas is compressed isothermally, then its pressure
increases
decreases
remains the same
first increases and then decreases
Solution
According to isothermal condition,
$p V=K$ (constant)
i.e. $\quad p \propto \frac{1}{V} \quad\left[\because p=\frac{K}{V}\right]$
So, in isothermal compression, when volume decreases, pressure increases.
