The net movement of water toward an area with higher solute concentration is -
diffusion
osmosis
condensation
evaporation
What condition causes for the vacuole to fill with water?
There is a higher concentration of water outside of the cell than inside the cell.
The temperature of water inside the cell is higher than outside the cell.
There is a lower concentration of water outside the cell than inside the cell.
The temperature of water outside the cell is higher than outside the cell.
What is the role of the cell membrane?
It is impermeable and does not allow water to enter the cell.
It is permeable and allows for water and solutes to move into and out of the cell.
It removes water from the cell.
It is semi-permeable and allows water to enter and leave the cell.
If a fish is placed in a hypotonic solution, what will occur?
Water will move into the cells of the fish.
Water will move out of the cells of the fish.
Water will move into and out of the cells of the fish equally.
Salt will be pumped into the cells of the fish.
In the winter, salt is scattered across the roads. The salt sometimes makes its way to plants on the side of the road. These plants usually die shortly after this happens. Why?
The solute concentration is higher outside the cells than inside, causing the water to move out of the cells.
The solute concentration is higher inside the cells than outside, causing the water to move out of the cells.
The solute concentration is higher outside the cells than inside, causing the salt to move into the cells.
The solute concentration is higher inside the cells than outside, causing the salt to move into the cells.
Why is the solution side of the u-tube going to rise?
Water moves from a lower concentration of water to a higher concentration of water.
The solutes from the solution side are going to move to the pure solvent side.
The amount of water and solute is the same on both sides of the membrane.
Water moves from a higher concentration of water to a lower concentration of water.
What property of water states that water molecules are attracted to other surfaces?
cohesion
osmosis
surface tension
adhesion
What property of water states that water is attracted to other water molecules?
cohesion
surface tension
osmosis
adhesion
Why does a water molecule have positive charges and a negative charge?
The valence electrons of oxygen spend more time around the hydrogen atoms, making the hydrogens negative.
The valence electrons of oxygen and hydrogen are shared, but they spend more time around the oxygen, making it negative.
The protons of oxygen are given to hydrogen in the covalent bond, making the hydrogen positive.
The electrons of hydrogen are given to oxygen when they form the ionic bond, making oxygen negative and hydrogen positive.
In a solution of saltwater, what is the solvent?
water
salt
milk
hydrogen
What property of water makes it a universal solvent?
Water has a high specific heat
Water has high surface tension
Water is polar
Water is adhesive
Which of the following is not true about water?
There is an uneven sharing of electrons.
Water is non-polar.
Water is polar.
Water is held together by hydrogen bonds.
The atoms of water (hydrogen & oxygen) are held together by _______bonds.
hydrogen
covalent
ionic
weak
Which of the following best describes the solubility of this compound as temperature inreases?
As temperature increases, solubility decreases.
As temperature increases, solubility increaeses.
As temperature increases, solubility remains the same.
As temperature increases, solubility decreases then increases.
Which of the following would not cause a solute to dissolve faster?
increase temperature
stirring
crushing the solute
decreasing pressure
