For gas absorption, low viscosity solvents are preferred, because of their ____________________?

Pressure drop through plate tower as compared to that through packed tower, for the same duty will be___________________?

Desulphurisation of petrol is done in a _____________________?

Henry’s law states that the ________________________?

A 25 cm × 25 cm × 1 cm flat sheet weighing 1.2 kg initially was dried from both sides under constant drying rate conditions. It took 1500 seconds for the weight of the sheet to reduce to 1.05 kg. Another 1m × 1m × 1cm flat sheet of the same material is to be dried from one side only. Under the same constant drying rate conditions, the time required for drying (in seconds) from its initial weight of 19.2 kg to 17.6 kg is ____________________?

Swenson-Walker crystalliser is a __________________ unit ?

The change in enthalpy, when a unit quantity of gas is absorbed by relatively large quantity of adsorbent (on which a definite concentration of the adsorbed gas already exists) is termed as the_________________?

Moisture in a solid exerting an equilibrium vapour pressure equal to that of the pure liquid at the same temperature is called the ___________________ moisture ?

For a binary mixture distillation process, the degree of freedom is 2. However, if the pressure is fixed in this process, the number of independent variables in this process will be ___________________?

With increase in temperature, the leaching rate increases because of the _____________________?
