Moth balls and camphor are materials that undergo ...............(sublimation/vaporization).

The pressure on a sample of water at its triple point is reduced while the temperature is held constant .Which phases changes are favoured? (1) melting of ice (2)sublimation of ice (3) vaporization of liquid water

Which element of group 15 undergoes sublimation?

Sublimation of camphor is a physical change. Explain.

Which of the following materials exhibits sublimation ?

Two balls each of mass 2kg (one at rest) undergo oblique collision is perfectly elastic, then the angle between their velocities after collision is

A homogeneous ball (mass=m) of ideal black material at rest is illuminated with a radiation having a set of photons (wavelength =lamda ), each with the same momentum and the same energy. The rate at whoch photons fall on the ball is n. the linear acceleration of the ball is

Two balls of same material and same surface finish have their diameters in the ratio 1:2. They are heated to the same temperature and are left in a room to cool by radiation, then the initial rate of loss of heat

Two rods of different materials having coefficient of thermal expansion alpha_(1), alpha_(2) and young's modulii Y_(1) ,Y_(2) respectively are fixed between two rigid massive walls. The rods are heated such that they undergo the same increase in temperature. There is no bending of rods. If alpha_(1) :alpha_(2)=2 : 3 , the thermal stresses developed in the two rods are equal provided Y_(1) : Y_(2) is equal to
