Rate of evaporation is the same for every liquid.

The evaporating dish is made of

Evaporation of water is

Define : Evaporations

The rate of evaporation of water doubles with every rise in temperature by

Evaporation is the change of state from liquid to vapour by absorbing heat at a particular temperature.

The rate of expansion for the same liquid differs greatly in different temperature ranges.

Look at the figure and suggest in which of the vessels A, B,C, or D, the rate of evaporation will be the highest ? Explain.

A body is just floating on the surface of a liquid. The density of the body is the same as that of the liquid. The body is slightly pushed down. What will happen to the body?

An inverted cone of height H , and radius R is pointed at bottom. It is completely filled with a volatile liquid. If the rate of evaporation is directly proportional to the surface area of the liquid in contact with air (constant of proportionality k gt 0). Find the time in which whole liquid evaporates.

A child running a temperature of 101^F is given and antipyrin (i.e. a madicine that lowers fever) which cause an increase in the rate of evaporation of sweat from his body. If the fever is brought down to 98^@F in 20 min., what is the averatge rate of extra evaporation caused, by the drug ? Assume the evaporation mechanism to the only way by which heat is lost. The mass of the child is 30 kg. The specific heat of human body is approximately the same as that of water and latent heat of evaporation of water at that temperature is about 580 cal. g^(-1).
