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 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.
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 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.
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.

Are there more water vapor molecules above a beaker of water at a room temperature or a beaker of water at its boiling point?
boiling point

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.
Are there more water vapor molecules above a beaker of water at room temperature or a beaker of water at its boiling point?
There are more water vapor molecules above a beaker of water at its boiling point because the higher temperature causes more water molecules to evaporate into the air. This results in a higher concentration of water vapor over the boiling water compared to room temperature water.

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.
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 would happen if you did an experiment in which the iodine solution was placed in the Baggie and the starch was in the beaker?
The iodine solution in the baggie would diffuse into the beaker containing the starch. The iodine molecules would interact with the starch molecules, resulting in the formation of a dark blue or black color, indicating the presence of a starch-iodine complex.
What if someone heats a beaker containing water. And the temperature of the water increases which change to the water molecules occurs?
no one has an answer smh
