When dehydrated fruits and vegetables are placed in water, they slowly swell and return to original form. Why? Would a temperature increase accelerate the process? Explain.

When dehydrated fruits and vegetables are placed in water they slowly swell and return to original form why ? What is the effects of temperature on the process ?

STATEMENT - 1 : When dried fruits and vegetables are placed in water, they slowly get swollen. STATEMENT - 2 : It happens due to the phenomenon of osmosis.

A hollow sphere is filled with water through a small hole in it. It is hung by long thread and as water slowly flows out from the hole at the bottom, one finds that the periods of oscillation first increases and then decreases. Explain. Why.

Pragya tested the solubility of three different substances at different tem¬ peratures and collected the data as given below (results are given in the following table, as grams of substance dissolved in 100 grams of water to form a saturated solution).Pragya makes a saturated solution of potassium chloride in water at 353 K and leaves the solution tocool atroom temperature. What would she observe asthesolution cools ? Explain

Why does micelle formation take place when soap is added to water? will a micelle be formed in other solvents such as ethanol also?

Protein found in a biological system with a unique three dimensional structure and biological activity is called a native protein. When a protein in its native form, is subjected to a physical change like change in temperature or a chemical change like, change in pH, denaturation of protein takes place. Explain the cause.

Compute the bulk modulus of water from the following data: Initial volume = 100.0 litre, Pressure increase = 100.0 atm (1 atm = 1.013 xx 10^5 Pa). Final volume = 100.5 litre. Compare the bulk modulus of water with that of air (at constant temperature). Explain in simple terms why the ratio is so large.
