Question:-

➡ It is found on heating a gas,its volume increases by 50% and the pressure decreases to 60% of its original value. If the original temperature was -15°C, find the temperature to which it was healed.

Answer:-

➡ The required temperature is -40. 8°C

Solution:-

Let us assume that,

And given that,

Now,

Now,

And,

Now,

we know that,

So,

Hence, the temperature at which it was healed is -40.8°C.
