A cell has an osmotic pressure of 15 atmospheres and water evaporates from it until the enclosed sap is subjected to a tension of 12 atmospheres. At this moment what would be the OP, TP, and DPD of the cell?

A gas at 0^@C and 1 atmospheric pressure occupies 2.5 litres. What change in temperature would be necessary if the pressure is to be adjusted to 1.5 atmospheres and the gas has been transferred to a 2.0 litre container?

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 ?

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 ?

An air bubble doubles in radius on rising from bottom of a lake to its surface. If the atmosphere pressure is equal to that due ot a column of 10 m of water, then what will be the depth of the lake. (Assuming that surface tension is negligible)?

When an air bubble of radius 'r' rises from the bottom to the surface of a lake, its radius becomes 5r//4 (the pressure of the atmosphere is equal to the 10 m height of water column). If the temperature is constant and the surface tension is neglected, the depth of the lake is

Active absorption of water from the soil by the root is mainly affected by osmotic concentration of the cell sap of leaves

An aqueous solution of sucrose ( C_(12)H_(22)O_(11) ) having a concentration of 34.2gram/ litre has an osmotic pressure of 2.38 atmospheres at 17^(@) C. For an aqueous solution of glucose ( C_(6)H_(12)O_(6) ) to be isotonic with this solution , its concentration should be :

If water potential of a cell is - 30 bar and osmotic potential is - 62 bar then what is the value of the TP developed in the cell.

Cell A has osmotic potential of -18 bars and pressure potential of 8 bars, whereas, cell B has osmotic potential of -14 bars and pressure potential 2 bars. The direction of flow of water will be
