Question

Help me please( ╹▽╹ )​

Answer 1

Lower temperature

Let's verify

• Pressure=P
• volume=V
• Temperature=T

As per Boyles law

$\\ \rm\Rrightarrow V\propto \dfrac{1}{P}$

As per Charles law

$\\ \rm\Rrightarrow V\propto T$

$\\ \rm\Rrightarrow T\propto \dfrac{1}{P}$

So

At higher altitudes lower the pressure so lower the temperature
