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 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.
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.
Do water atoms expand or multiply when heated?
Water atoms do not expand or multiply when heated. When water is heated, the heat energy causes the water molecules to move faster and farther apart, which results in the expansion of the water volume. The number of water molecules remains the same.
What happens when rock salt and water are heated and stirred?
When rock salt is heated and stirred in water, it dissolves into the water to form a saline solution. The heat helps to speed up this process by providing energy for the salt molecules to break apart and mix with the water molecules. Stirring also enhances the dissolution process by ensuring thorough mixing of the salt and water molecules.
What happens to water molecules when water is heated from 90 to 110 Celsius?
The liquid molecules are transformed in gas molecules.
What happens to molecules when water is heated from 90 to 110 Celsius?
The liquid molecules are transformed in gas molecules.
What do the lines on a phase diagram present?
what happens to water molecules when they are heated
How do you heat a beaker of water?
With a heat source, slowly so as to not shatter the beaker.
As evaporating water enters into the atmosphere what happens?
Its molecules become heated.

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 happen in the evaporating dish as water in thr beaker is being heated?
After the total evaporation of water a small solid residue can remain in the beaker.
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 happened to the water molecules when they are heated?
the molecules evapourate
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.
