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.
How can the rate of evaporation of water from an open beaker be decreased?
Place a lid over the beaker, and store in a cool place.
If a cold piece of metal is placed in an equal mass of warm water will the final temperature be closer to the original temperature of the metal or the water?
Temperature of the water
What effect does the initial temperature of the water have on change in temperature of the water after the hot metal is added?
When hot metal is added into the water then the metal looses its energy into the water and this heat is gained by the water, so the temperature gets increases when hot metal added into it i.e final temperature is greater than initial temperature of water.
Will a temperature of a beaker of water increase or decrease when its mixed with salt?
This is the typr of experiment that is performed with a 'Slurry' of ice and water in the beaker, and not just room temperature water. Adding salt to a slurry will cause some of the ice to melt. When ice melts, the temperature of the solution will drop, and potentially below the freezing point of pure water.If the water and salt are at room temperature, the mixing will yield no significant changes in temperature.
When sodium metal is dropped into a beaker of water a chemical reaction occurs that increases the temperature of the water This is an example of what?
You think probable to an exothermic reaction.
What experimental method can determine the density of metal?
Density is the mass of the object divided by its volume. By this principle, to determine the density of a metal, place the metal onto a scale to measure its mass. After this, place the metal into a beaker of water and measure the volume change in the beaker. Divide the mass by the volume and you get the density.
What collects on the outside of the beaker if you place a 5 ml water and few ice cubes in the beaker?
when ice cubes place in the beaker, outside of the beaker have a formation of water drops. by. JD
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
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
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.
When a water with blue ink evaporates and than condenses on the metal tray and drips down to a beaker what colour will the water be in the beaker?

When ammonium chloride dissolves in a beaker of water the beaker becomes cold to the touch explain this phenomenon?
When the ammonium chloride dissolves in the water, it is an endothermic reaction. The energy for the reaction comes from the water. Since the water is losing energy, the temperature of the solution decreases, which in turn decreases the temperature of the beaker because of heat transfer.
If beaker a had 250ml of water beaker b had 500ml water are warmed from 10 celsius to 20 celsius what one requires more heat?
Because there is a greater volume of water in beaker B, the beaker would have to be heated for a longer period of time to reach the same temperature as beaker A. If your desire is to have both beakers warmed to the same temperature at the same time, beaker B would require the addition of more heat (because there is more water inside it).
The temperature of hot water in a beaker was 86 C.The water cooled by 2 C every minute.What was the temperature of the water after 15 minutes?
116
