Study the given figure carefully and select the true and false:- statement(s) regarding it. (a) Solution of chamber B has a lower water potential. (b) Solutio of chamber A has a lower solute potential (c). Osmosis occurs from chamber A to B. (d) Solution f cham ber B has higher solute potential. (e) At equlibrium both chambers have equal water potential. (f) If one chamber has a Psi of -2000 kPa and the other -1000kPa then chamber with Psi of -1000 kPa has the highger Psi

Statement-I: 1M solution of Glauber's salt is isotonic with 1M solution of KNO_(3) . Because Statement-II: Solutions having same molar concentration fo solute may or may not have same osmotic pressure.

Match the items given in Column - I and Column - II. {:(,"Column - I",,"Column - II"),((A),"Saturated solution",(1),"Solution having same osmotic pressure at a given temperature as that of given solution."),((B),"Binarysolution",(2),"A solution whose osmotic pressure is less than that of another."),((C ),"Isotonic solution",(3),"Solution with two components."),((D),"Hypotonic solution",(4),"A solution which contains maximum amount of solute that can be dissolved in a given amount of solvent at a given temperature."),((E ),"Solid solution",(5),"A solution whose osmotic pressure is more than that of an other."),((F),"Hypertonic solution",(6),"A solution in solid phase."):}

Each phase of a material can exits only in certain regions of pressure and temperature . P-T phase diagrams, in which pressure is plotted versus temperature, show the regions corresponding to various phases and phase transformations . P-V diagrams, on the other hand , can be used to study pressure volume relationship at a constant temperature. If the liquid and gaseous phases of a pure substances are heated together in a closed container, both the temperature and the vapor pressure will increase until a point is reached at which the two phases can no longer be distinguished from one another. The temperature and pressure at which this occurs are called the critical temperature and pressure. Exceeding either of these parameters, by itself ,will cause the "gas"//"liguid" phase transition to disappear. if the other variable is then changed as well, while the first variable is maintained above its critical point , a gradual transition will occur between the gaseous and liquid phases, with no clear boundary.(The liquid and solid phases, on the other hand , maintain a distinct boundary at all pressure above the triple point). Shown in figure is a combined P-T phase diagram for material A and B . Which is true about the substance in figure?

Figure shows a container filled with a liquid of density rho . Four points A, B, C and D lie on the vertices of a vertical square. Points A and C lie on a vertical line and points B and D lies on a horizontal line. Choose the correct statement(s) about the pressure at the four points.

State whether the following statements are true or false? Also give reasons for your answers. a) Only one line can pass through a given point. b) All right angles are equal. c) Circles with same radii are equal. d) A line segment can be extended on its both sides endlessly to get a straight line. e) From the figure, AB gt AC .

Two blocks A and B are joined together with a compressed spring. When the system is released, the two bloks appear to be moving with unequal speeds in the opposite directions as shown in figure. Select incorrect statements(s) :
