Question

A LITRE OF AIR HEATED FROM 27 DEGREE CELSIUS TO 177DEGREE CELSIUS AT CONSTANT PRESSURE. FIND THE VOLUME?

Answer 1

A litre of heat kuch bhi

Answer 2

Given that,

Volume = 1 L

Initial temperature = 27°C = 300 K

Final temperature = 177°C = 450 K

Here, Pressure is constant.

We need to calculate the final volume

Using relation of volume and temperature

$\dfrac{V_{1}}{T_{1}}=\dfrac{V_{2}}{T_{2}}$

$V_{2}=\dfrac{V_{1}}{T_{1}}\times T_{2}$

Where, $V_{2}$ = Final volume

$V_{1}$ =Initial volume

$T_{1}$ = Initial temperature

$T_{2}$ = Final temperature

Put the value into the formula

$V_{2}=\dfrac{1}{300}\times450$

$V_{2}=1.5\ L$

Hence, The final volume is 1.5 L.
