<h3>Types of Osmosis</h3>

Osmosis is of two types:

Endosmosis– When a substance is placed in a hypotonic solution, the solvent molecules move inside the cell and the cell becomes turgid or undergoes deplasmolysis. This is known as endosmosis.

Exosmosis– When a substance is placed in a hypertonic solution, the solvent molecules move outside the cell and the cell becomes flaccid or undergoes plasmolysis. This is known as exosmosis.

There are some variations or types of osmosis on the basis of the direction of the movement of solvent molecules.

  • Reverse osmosis is a method of separation that is used to force a solvent through a semi-permeable membrane resulting in solute molecules on one side and solvent molecules on the other side.

  • Reverse osmosis is different than the forward osmosis in that reverse osmosis utilized hydraulic pressure to force the solvent against the osmotic pressure.

  • Forward osmosis is another variation of osmosis where the osmotic pressure gradient is used to induce the flow of water from the sample solution to separate the solutes.

  • Forward osmosis uses a draw solution with a higher concentration of solute, which extracts the solvent molecules from the sample solution; thus, resulting in the separation of solute and solvent in the sample solution.

  • Endosmosis is the movement of water into the cell which occurs when a cell is placed in a solution having a higher concentration of water than the cell.

  • Exosmosis is the movement of water out of the cell which occurs when a cell is placed in a solution having a higher concentration of solute than the cell.

9966 [12]

Answer:

The internal energy of a system <u>is the sum of the potential and kinetic energies of the components</u>

Explanation:

Internal energy is defined as the sum of two types of energy: kinetic energy and potential energy.

Kinetic energy is defined as the sum of all the kinetic energies that each element has within a system with respect to its center of mass. It is caused by the movement of particles. Meanwhile, the potential energy is the energy that is associated with each of the interactions. Potential energy is associated with the constituents of matter, of the electrostatic energy of each atom that is inside the molecules.

kap26 [50]
  • Convert Kelvin to °c

(a) 67°c

Formula:-

k=°c+273

°c = 273 - k

°c = 273-67= 206 °c

(b) 1671 k

k=°c+273

°c = 273 - k

°c= 273-1671 = -1398°c
