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?
Acetone molecules evaporate when you add heat to a beaker of liquid acetone.
What happens to the water molecules in a beaker as the water that is heated from 10 c to 90c?
The water molecules would speed up, but not to the point of boiling.
What is water-water bonds called in a beaker of water?
The bonds beween the water molecules, H2O, are called hydrogen bonds.
Description of osmosis?
osmosis means the movement of water from a high concentration gradient to a low concentration gradient, through a SEMI-permable membrane, osmosis is 'complete' whene both sides are in they state of equalibrium this means when the water molecules are evenly spread out. e.g. a potato clyinder in a water beaker, the water particles in the potato is greater than in the beaker of water, and so as the definition says '...from a high to low concentration...' the water molecules transferr from the potato to the beaker of water.

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

Acetone molecules evaporate when you add heat to a beaker of liquid acetone.
What happens to the water molecules in a beaker as the water that is heated from 10 c to 90c?
The water molecules would speed up, but not to the point of boiling.
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 will happen 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 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

Water will enter the sac and it will swell
What is water-water bonds called in a beaker of water?
The bonds beween the water molecules, H2O, are called hydrogen bonds.
When CuSo4 solution is placed in a beaker containing water it turns blue?
The molecules of copper sulphate solution mixes with the water molecules due to diffusion thereby making the water blue.
