The gases are at absolute temperature and respectively. The ratio of average kinetic energy of their molecules is:
Which of the following is not the assumption of kinetic theory of gases?
Particles are in constant, random motion
Negligible volume of particles
Elastic collisions
Strong intermolecular forces
The gases are at absolute temperature and respectively. The ratio of average kinetic energy of their molecules is:
When the temperature is raised, the viscosity of the liquid decreases. This is because of:
Decreased volume of the solution
Increase in temperature increases the average kinetic energy of molecules which overcome the attractive force between them
Decreased covalent and hydrogen bond forces
Increased attraction between the molecules
