HEYA!!

An ideal gas is at temperatureof 127℃ .it is heated at constant pressure until its volume becomes 1.5 times. what will be new temperature?

________

COPIED ANSWER REPORTED!!

Answer 1

First of all, solving gas laws numericals is very easy if you are able to understand the question properly. Here, we can easily use Charles' law to find out the new temperature.

Charles' law states that at a constant pressure, the volume of a fixed mass of a dry gas is directly proportional to its absolute temperature.

So, we can say : V ∝ T

Or, V = k × T (K is a constant)

Or, V/T = k = constant.

Or, V1/T1 = V2/T2 = constant.

Let us note down the given informations immediately to solve the above numerical easily :

✔ V1 = V (say)

✔ V2 = 1.5 V

✔ T1 = 127°C = 400 K

✔ T2 = ?

Applying Charles' law we will get :

V1/T1 = V2/T2

Or, V/400 = 1.5 V/T2

Or, T2 = 600 K

Or, T2 = 327°C [ANSWER]
