Assume that benzene is insoluble in water. The normal boiling points of benzene and water are 80.1 and 100°C respectively. At a pressure of 1 atm, the boiling point of a mixture of benzene and water is
80.1°C.
less than 80.1°C.
100°C.
greater than 80.1°C but less than 100°C.

8.
Pick out the wrong unit conversion of heat transfer co-efficient.
1 kcal/m2.hr.°C = 0.2048 BTU/ft2.hr. °F. = 1.163 W/m2.°K
1 kcal/m2.hr.°K = 1.163 W/m2.°C
1 W/m2 . °C = 0.1761 BTU/ft2.hr.°F.
1 BTU/ft2.hr.°F = 4.88 kcal/m2.hr.°C = 20.44 kJ/m2.hr°C = 5.678 W/m2.°C.

Diffusion is that property by virtue of which a perfume bottle when opened up in a room, makes the whole room fragrant with its smell. If a perfume 'X' diffuses twice as fast as another perfume 'Y'; what is the molecular weight of 'Y', if the vapor density of gas 'X' is 2 ? Molecular weight of gas 'X' is to be assumed to be 2.
