When you put salt water in a beaker with potato cells, the cells will lose water through a process called osmosis. Since the salt concentration outside the cells is higher than inside, water moves out of the potato cells to balance the concentration. This causes the cells to shrink and become plasmolyzed, leading to a wilting or shriveling appearance in the potato.
What else can I help you with?
34. If liver cells are put in a beaker with a solution containing the same solute concentration as that found inside the cell the beaker would contain a(n)?
If liver cells are placed in a beaker with a solution that has the same solute concentration as the inside of the cells, the beaker would contain an isotonic solution. In this scenario, there would be no net movement of water into or out of the cells, maintaining their shape and function. The cells would remain stable, as the osmotic pressure is balanced.
Beaker X contains 50cm3 of marbles while Beaker Y contains 100cm3 of water. When all the water in Beaker Y is poured into Beaker X what is the volume of the water in Beaker X?
The volume of the water in Beaker X will be 100cm3, as you are not adding any more water to the equation (50X+100Y is not 150Y or X, but 50X+100Y) The total volume of matter in Beaker X will be 150cm3, and if the beaker is labelled, the volume measure will indicate 150cm3 due to the displacement of water. But as the answer to your question, the volume of water in Beaker X must be 100cm3 even though visual indicators will not show this due to the displacement of water by marbles
How does is the temperature of beaker measure in water?
The temperature of a beaker is typically measured using a thermometer that is placed in the water inside the beaker. The thermometer will provide a reading of the water temperature, which indirectly reflects the temperature of the beaker as well.
How do you calculate mass of water in the beaker by difference?
To calculate the mass of water in a beaker by difference, first weigh the empty beaker and record its mass. Next, fill the beaker with water and weigh it again to obtain the combined mass of the beaker and water. Subtract the mass of the empty beaker from the total mass to find the mass of the water alone. This method allows for an accurate measurement by accounting for the container's weight.
Can water in a beaker be made to boil by placing in a bath of boiling water?
Yes, as the water in the beaker will finally get the same water temperature in the water bath.

What happened to the water in the beaker?
The water in the beaker evaporated or was poured out.

Are there more particles in a beaker with a large amount of water in it or a beaker with a small amount of water in it?
There are more particles in the beaker with a large amount of water compared to a beaker with a small amount of water, assuming the water is the only substance present. This is because the volume of water in the larger beaker contains more individual water molecules than the volume of water in the smaller beaker.
Beaker A contains water at a temperature of 15 degrees C beaker B contains water at a temperature of 37 degrees C Which beaker contains water molecules that have greater kinetic energy and why?
Beaker A: 15 C Beaker B: 37 C Beaker B contains water molecules that have the greater kinetic energy (on average). Since beaker B is at a higher temperature than beaker A, the water molecules must be moving faster in beaker B than in beaker A (on average). If heat is being applied to the beakers, then the increased amount of heat applied to beaker B is greater, and the heat will cause the water molecules in beaker B to move faster than the water molecules in beaker A (on average). Kinetic energy = (1/2) (mass) (velocity)^2 Since the velocity of the a water molecule in beaker B is on average greater than the velocity of an average water molecule in beaker A, the water in beaker B has a higher kinetic energy.

What is happening to the red blood cell and cell in beaker?
In a beaker containing a solution, red blood cells can either swell or shrink depending on the solution’s tonicity. If the solution is hypotonic (lower solute concentration than inside the cells), water enters the cells, causing them to swell and potentially burst. Conversely, in a hypertonic solution (higher solute concentration), water exits the cells, leading to cell shrinkage. This movement of water across the cell membrane is driven by osmotic pressure.
Impact of red blood cells if placed in beaker with water and little salt?
When red blood cells are placed in a beaker with water and a little salt, they experience a hypotonic environment. The lower concentration of solutes outside the cells causes water to flow into the cells through osmosis, leading to swelling. If the osmotic pressure exceeds the cell's membrane capacity, the cells may burst, a process known as hemolysis. However, with only a little salt, some cells may remain intact while others could still undergo mild swelling.
How do you calculate mass of water in the beaker by difference?
To calculate the mass of water in a beaker by difference, first weigh the empty beaker and record its mass. Next, fill the beaker with water and weigh it again to obtain the combined mass of the beaker and water. Subtract the mass of the empty beaker from the total mass to find the mass of the water alone. This method allows for an accurate measurement by accounting for the container's weight.
How much does a beaker weigh with 40ml of water?
The weight of the beaker with 40mL of water will depend on the density of the water and the material of the beaker. Water has a density of 1g/mL, so the weight can be calculated by multiplying the density by the volume. The weight of the beaker itself will need to be accounted for as well.
How is water droplets formed in the inner most surface of the beaker?
Water droplets form on the inner surface of a beaker when the water vapor in the air comes into contact with a cold surface, causing it to condense into liquid water. This occurs due to the temperature difference between the cold surface of the beaker and the surrounding air.
Can water in a beaker be made to boil by placing in a bath of boiling water?
Yes, as the water in the beaker will finally get the same water temperature in the water bath.
