Question

A sample of argon gas is cooled and its volume had changed from 380 ml to 250 ml.if its final temperature was -55°c,what was its original temperature?[pressure constant]​

Answer 1

Answer:

200

Explanation:

from ideal gas equation, PV = nRT

So, this gives V=

P

nRT

so, V is proportional to absolute temperature and inversely proportional to the pressure of the gas

Now temperature is made half and pressure is made 2 times

So, clearly the volume becomes one-fourth of it's original value.
