Question

The volume of a given mass of a gas is 1000ml at 100degree centigrade. If pressure is kept constant at what temperature will the volume of 200ml​

Answer 1

Answer:

v1/t1=v2/t2

1000/373=200/x

5x=373

74.6 is the temperature

hope it helps...

Answer 2

Temperature = 74.6 K

Explanation:

We known that the formula of Ideal gas equation is-

              $PV=nRT$

where     P= Pressure

               V= Volume

               n= no. of moles

               R= Universal gas constant (8.314 J/K. mol)

                T= Temperature

For same gas R and n will be constant and in question pressure P is also kept constant. So, in this case volume is directly proportional to temperature.

                                             $V \alpha T$

                                            $\frac{V_{1} }{V_{2} }=\frac{T_{1} }{T_{2} }$            .......(i)

Given $T_{1} =100^{0}C=373K$

$V_{1}=1000ml$ ,  $V_{2}=200ml$

Put the above values in equation (i)

                   $\frac{1000ml}{200ml}=\frac{373K}{T_{2}}$

                     ${T_{2}=74.6 K$

Therefore, the temperature should be 74.6 K.
