- Heat of transition is the heat evolved or absorbed, when a substance is converted from
- __________ fuels require the maximum percentage of 'excess air' for complete combustion.
- A liquid is in equilibrium with its vapor at its boiling point. On an average, the molecules in the liquid and gaseous phases have equal
- The vapour pressure of water is given by, in Psat = A - (5000/T), where A is a constant, Psat is the vapour pressure in atm. and T is the temperature in K.The vapor pressure of water in atm. at 50°C is approximately
- An equation for calculating vapour pressure is given by, log10 P = A - B(t + c). This is called the
-
The combustion equations of carbon and carbon monoxide are as follows:
C + O₂ = CO₂, ΔH = - 394 kJ/kg . mole CO + 1/2 O₂ = CO₂, ΔH = - 284.5 kJ/kg. mole.
The heat of formation of CO is __________ kJ/kg. mole. - In case of a ternery system involving two liquid components and a solute, the ratio of the concentration of the solute in the two phases at equilibrium is called the distribution co-efficient. The distribution co-efficient depends upon the
- Enthalpy change resulting, when unit mass of solid is wetted with sufficient liquid, so that further addition of liquid produces no additional thermal effect, is called the heat of
