Viscosity of a liquid is a measure of ___________

Which of the following gas(es) always show positive deviation from ideal behaviour?

When the gas behaves ideally, the compression factor Z is ___________

What is the dominant intermolecular force or bond that must be overcome in converting liquid methanol to a gas?

Identify the correct mathematical expression of Graham's law of diffusion __________

The partial pressure of dry gas is ____________

The absolute zero is _____________

V/T = constant is _____________ law.

The standard atmospheric pressure is the pressure that supports a column of mercury exactly ___________ high at 0° C at sea level.

The unit of pressure is _____________

Pressure is _____________

Which of the following diagrams correctly describes the behaviour of a fixed mass of an ideal gas? (T is measured in K)

Assertion: Critical temperature of CO₂ is 304K, it can be liquefied above 304K.
Reason : For a given mass of gas, volume is to directly proportional to pressure at constant temperature

The variation of volume V, with temperature T, keeping pressure constant is called the coefficient of thermal expansion ie \(\alpha =\frac { 1 }{ V } { \left( \frac { \partial V }{ \partial T } \right) }_{ P }\) For an ideal gas a is equal to ___________

Consider the following statements
i) Atmospheric pressure is less at the top of a mountain than at sea level
ii) Gases are much more compressible than solids or liquids
iii) When the atmospheric pressure increases the height of the mercury column rises.
Select the correct statement

Use of hot air balloon in sports at meteorological observation is an application of __________________

The value of universal gas constant depends upon __________

The temperatures at which real gases obey the ideal gas laws over a wide range of pressure is called ____________-

When an ideal gas undergoes unrestrained expansion, no cooling occurs because the molecules _____________
