13 Questions

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?
2. What is SI unit of viscosity coefficient (η)?
3. Increase in kinetic energy can overcome intermolecular forces of attraction. How will the viscosity of liquid be affected by the increase intemperature?
4. The interaction energy of London force is inversely proportional to sixth power of the distance between two interacting particles but their magnitude depends upon
5. Dipole-dipole forces act between the molecules possessing permanent dipole. Ends of dipoles possess ‘partial charges’. The partial charge is
6. A plot of volume (V ) versus temperature (T ) for a gas at constant pressure is a straight line passing through the origin. The plots at different values of pressure are shown in Fig. 5.1. Which of the following order of pressure is correct for this gas?
7. Which of the following property of water can be used to explain the spherical shape of rain droplets?
8. Atmospheric pressures recorded in different cities are as follows:

Consider the above data and mark the place at which liquid will boil first.
9. 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 above data what would be the order of liquefaction of these gases? Start writing the order from the gas liquefying first
10. "A person living in Shimla observed that cooking food without using pressure cooker takes more time. The reason for this observation is that at high altitude:"
11. How does the surface tension of a liquid vary with increase in temperature?
12. 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?
13. Which curve in this figure represents the curve of ideal gas?
