Question
If an ideal gas occupies a volume of 10.0 L at 25.0 degree C and a pressure of 1.00 atm, what volume would it occupy at 50.0 degree C assuming the pressure is unchanged? 20.0 L 10.8 L 8.56 L 5.0 L Which phase is present at 23 atm and -81 degree C? supercritical fluid liquid gas solid What is the strongest intermolecular force between CCl_4 molecules? induced dipole - induced dipole hydrogen bonding dipole - dipole ionic bonding Order the compounds in decreasing vapor pressure at 25 degree C. I > II > IV > III I > IV > II > III III > IV > I > II IV > I > III > IIExplanation / Answer
Ans 43. B) 10.8 L
According to ideal gas law, pV = nRT
volume of gas is directly proportional to temperature
where V is in litre and temperature in kelvin
50o C = 323 K
25o C = 298 K
V1 T2 = V2 T1
10 . 323 = V2 . 298
V2 = (10 x 323 ) / 298
V2 = 10.8 L
