Question

the volume of a given mass of a gas is 100 ml at hundred degree Celsius if pressure is kept constant at what temperature will the sample have the volume of 200ml

Answer 1

Answer: 186.5 K

Explanation:

Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$     (At constant pressure and number of moles)

${V_1\times T_1}={V_2\times T_2}$

where,

$V_1$ = initial volume of gas  = 100 ml

$V_2$ = final volume of gas  = 200 ml

$T_1$ = initial temperature of gas  =$100^0C=(100+273)=373K$

$T_2$ = final temperature of gas  = ?

${100\times 373}={200\times T_2}$

$T_2=186.5K$

Therefore, the the sample will have a volume of 200 ml at 186.5 Kelvin.

Answer 2

Answer:

the answer is (b) 473degree Celsius
