What happens when a membrane sac filled with large molecules of oil is suspended in a beaker of water?
Water will enter the sac and it will swell
What else can I help you with?
What will happen when a membrane sac filled with large molecules of oil is suspended in a beaker of water?
The oil molecules will not mix with the water because they are hydrophobic, causing the oil-filled sac to remain intact. The oil sac will float in the water due to the difference in density between oil and water. Over time, the oil molecules may slowly diffuse out of the sac into the water, depending on the permeability of the membrane.
If a beaker contains glucose and is permeable to glucose what will happen to the glucose?
If a beaker containing glucose is permeable to glucose, then the glucose will go through the beaker.
How do you use osmiosis in a sentence?
Osmosis is a process by which molecules pass through a semipermeable membrane from a less concentrated solution to a more concentrated one. An example sentence using osmosis could be: "During osmosis, water molecules moved from the beaker with a lower salt concentration to the one with a higher salt concentration."
Which part of the molecules will face the air when a single layer of phospholipid molecules coats the water in a beaker?
The hydrophilic (polar) head of the phospholipid molecules will face the air, while the hydrophobic (nonpolar) tails will be oriented towards each other, forming a bilayer that shields the water inside the beaker.
Why drop of ink can spread in a beaker without stirring?
This is called diffusion. If you just leave the ink in the beaker for a while, it will eventually spread out around the beaker and all of the water will have color. For example: This is just like a restaurant, there is non-smoking half of the restaurant and there is a smoking half. The smoke will eventually spread out front he smoking corner to the non-smoking corner. Another example: If you pee in the pool, the pee will eventually spread out through the pool.
What will happen if a membrane sac filled with large molecules of oil is suspended in a beaker of water?
If a membrane-bound sac filled with large molecules of oil is suspended in a beaker of water, water will start to enter the sac. The sac will then swell.
Why did the starch not enter the beaker?
The starch did not enter the beaker because the membrane of the dialysis tubing is selectively permeable, allowing only smaller molecules, like glucose and water, to pass through. Starch molecules are too large to pass through the pores of the membrane, thus they were unable to enter the beaker.

What happens to thermal energy in a beaker when it is cooled down?
When a beaker is cooled down, thermal energy is transferred from the beaker to the surroundings. The molecules in the beaker lose kinetic energy, which causes the temperature of the beaker to decrease. This transfer of thermal energy continues until the beaker reaches thermal equilibrium with its surroundings.
When you sit a beaker of hot water on a table what happens to the motion of the molecules that make up the table?
They vibrate faster
What do you think would happen to the osmotic pressure if you replaced the deionized water in the right beaker with 9.00 MM albumin in that run?
If you replace the deionized water with 9.00 MM albumin in the right beaker, the osmotic pressure will increase. This is because albumin has molecules that cannot pass through the semipermeable membrane, causing water to move from the left beaker to the right beaker to try to equalize the concentration of solutes on both sides of the membrane, increasing the pressure.
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 happens to acetone molecules when you add heat to a breaker of liquid acetone?
When heat is added to a beaker of liquid acetone, the acetone molecules gain energy and begin to evaporate into the air as a gas. The increased temperature causes the molecules to move faster and escape the liquid phase.
When a mixture of starch and glucose is put into a bag made from partially permeable membrane and is put in a beaker so after 20 minutes what change will take place in the contents of bag?
After 20 minutes, the glucose molecules will diffuse out of the bag through the partially permeable membrane because they are smaller in size than the starch molecules. The starch molecules, being too large to pass through the membrane, will remain inside the bag.
What happens to the volume of a beaker when ice melts in it?
The volume of a beaker doesn't change, it's a beaker. What your were probably trying to ask is what happens to the volume of the ice when it melts. The volume decreases; water is special. Unlike other substances when it freezes it expands. That is why ice floats, it is less dense then water.
What happens to acetone molecules when you add heat to a beaker of liquid acetone?
When heat is added to a beaker of liquid acetone, the acetone molecules gain kinetic energy and move more rapidly. This increased energy causes the acetone molecules to evaporate and transition to the gas phase. If the temperature is high enough, the acetone molecules may also undergo further reactions, such as decomposition or combustion.
How do small molecules pass through the cell membrane?
There are three types of transport for molecules across the cell membrane. 1 - Diffusion - Molecules move from an area of high concentration to an area of low concentration 2 - Osmosis - same idea as diffusion, but refers to the movement of WATER across a selectively permeable membrane. How can you change water concentration? Add a solute. If you have 2 250 ml beakers, connected and divided by a selectively permeable membrane, and one beaker contains a salt solution, the salt solution is "hypotonic" (hypo- less, tonic - water) to the water filled beaker. One will see a migration of water into the salt solution beaker. BOTH diffusion and osmosis rely on concentration gradients to perform their jobs. They always want "equilibrium" between both sides of the membrane. 3 - Active transport - Proteins embedded in the cell membrane move large molecules through the cell membrane or AGAINST the concentration gradient. The size one is obvious; If it's really big, it won't permeate the membrane. As for the concentration gradient, this means that it moves a molecule INTO the area with and already HIGHER concentration. If this happens with say... H+ molecules, it creates a potential difference - ie - Voltage across the membrane. Cellular respiration counts on this process to create ATP/Energy for the cell.
