The average Kinetic energy and Thermal energy are proportional to the:

Above the Critical temperature (T_C) of carbon dioxide:

A student forgot to add the reaction mixture to the round bottomed flask at 27 °C but instead he/she placed the flask on the flame. After a lapse of time, he realized his mistake, and using a pyrometer he found the temperature of the flask was 477 °C. What fraction of air would have been expelled out?

The pressure of a 1:4 mixture of dihydrogen and dioxygen enclosed in a vessel is one atmosphere. What would be the partial pressure of dioxygen?

The ease with which the electron cloud of a particle can be distorted is called its

Gases have much lower density than the solids and liquids because

The three states of matter of H₂O are in equilibrium at

Calculate the temperature of 4.0 mol of a gas occupying 5 dm³ at 3.32 bar. (R = 0.083 bar dm³K⁻¹mol⁻¹)

As the temperature increases, average kinetic energy of molecules increases. What would be the effect of increase of temperature on pressure provided the volume is constant?

Molecules in the interior of liquid experience intermolecular

Charles’ law states that pressure remaining constant, the volume of a fixed mass of a gas is

Surface tension decreases as the temperature is raised because

Calculate the total number of electrons present in 1.4 g of dinitrogen gas.

Gases possess characteristic critical temperature which depends upon the magnitude of intermolecular forces between the particles. Following are the critical temperatures of some gases. From the data what would be the order of liquefaction of these gases? Start writing the order from the gas liquefying first 

Surface tension results because

Gay Lussac’s law states that at constant volume, pressure of a fixed amount of a gas

Viscous force is

The van der Waals Equation adjusts the measured volume

Domestic power supply in India is

Capillarity results from a competition between the

The statements for laws of chemical combinations are given below. Mark the statement which is not correct.

Water has high surface tension and high capillarity because of

The van der Waals Equation adjusts the measured pressure

Atmospheric pressures recorded in different cities are as follows: Consider the above data and mark the place at which liquid will boil first. 

Which curve in Figure represents the curve of ideal gas?
