Five potato cylinders each measuring 40 ...

Five potato cylinders each measuring 40 mm were placed in concentrated salt solution for 24 hours. When they were re-measured their average length was 37 mm. Explain the reason.

### Step-by-Step Solution 1. **Understanding the Setup**: Five potato cylinders, each measuring 40 mm, were placed in a concentrated salt solution. This means that the salt concentration in the solution is higher than the concentration of solutes inside the potato cells. 2. **Osmosis Concept**: Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this case, water will move from the potato cells (where the solute concentration is lower) to the concentrated salt solution (where the solute concentration is higher). 3. **Effect of Concentrated Salt Solution**: When the potato cylinders are placed in the concentrated salt solution, water inside the potato cells moves out into the surrounding solution. This process continues until equilibrium is reached or until the cells lose a significant amount of water. ...

The length, breadth and thickness of a small uniform rectangular glass strip are 4.25cm , 6.25mm and 2.75mm . Its length is measured by vernier callipers of least count 0.01 cm and breadth and thickness were measured by screw gauge having least count 0.01mm . The percentage error in the measurement of volume of the strip is

In a vernier callipers, 10 vernier scale divisions coincide with 9MSD each of value 1mm. While measuring length of a cylinder using this calliper, main scale reading is 5.1 cm and 7th vernier division coincides with any main scale division. Whenm diameter of cylinder is measured, main scale reading is 1.7 cm and 3rd vernier division coincides with any main scale division. Calculate curved surface area of the cylinder with correct number of significant figures.

The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate, thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles "liter"^(-1) sec^(-1) . For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec^(-1) and atm. sec^(-1) The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances, thus, if the rate is found experimentally to be proportional to the alpha^(th) power of the concentration of one of the reactants A, to the beta^(th) power of the concentration of a second reactant B, and so forth, via., rate kC_(A)^(alpha) C_(B)^(beta)" " (1) the over-all order of the reaction is simply n = alpha +beta + ---------(2) Such a reaction is said to be of the alpha^(th) order with respect to the substance A, the beta^(th) order with respect to B and so on...
