(a) In the manufacture of paint, a specific solid additive is used to improve the property. The heat of fusion of the solid is 140 cal/g at a temperature of 10°C and pressure of 1 atm. The ratio of specific volume (m/kg) of solid and liquid is 1.120. Calculate the effect of saturated pressure on temperature (K/Pa).

Question
Transcribed Image Text:(a) In the manufacture of paint, a specific solid additive is used to improve the property. The
heat of fusion of the solid is 140 cal/g at a temperature of 10°C and pressure of 1 atm.
The ratio of specific volume (m³/kg) of solid and liquid is 1.120. Calculate the effect of
saturated pressure on temperature (K/Pa).
(b) A mixture of propane (1) and butane (2) is used as a fuel and the volume of the mixture
is given by:v (m³) = 0.0125 – 0.132 x1x2 – 0.0036 xỉ, where x, is the mole fraction of
component i. Calculate:
(i) the volume of propane when its mole fraction is 0.60.
(ii) the pure component volume of propane.
