Answer:
C. Water will flow into and out of the cell, but the overall net movement will be into the cell.
Explanation:
In a hypotonic solution, the concentration of water outside the cell is higher than inside the cell and the concentration of the solute is lower than inside the cell, therefore, water will flow in and out of the cell but the net movement of water will be from area having higher water concentration to lower concentration.
That means the net movement of water will be into the cell if a cell is placed into the hypotonic solution. Water moves in and out of a cell by the process called osmosis which is a type of diffusion.
This movement of water into the cell will swell cell and the cell can burst if it is not protected by a cell wall. Therefore the right answer is C.
Answer:
the latent heat as the heat supplied to increase the temperature of the substance is used up to transform the state of matter of the substance
Explanation:
It is due to the latent heat as the heat supplied to increase the temperature of the substance is used up to transform the state of matter of the substance hence the temperature stays constant. Hence the temperature remains constant as all the heat is used up and no external heat is released or absorbed
Answer:
If four samples have the same volume, the sample with the highest mass will have the highest density, i.e. sample Z.
Explanation:
The density expresses the amount of mass that occupies a given volume, and knowing the mass and volume of a solid, the density can be determined by the formula:
<em> ρ = m/V
</em>
From this formula it can be determined that <u>density is directly proportional to mass and inversely proportional to volume</u>.
Of the four samples, the highest mass is in the sample Z (312), so this sample has the highest density.
