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.
Tim poured 0.5 liters of water into a beaker and then added 300 milliliters more What was the total amount of water in the beaker?
The total amount of water in the beaker was 0.5 liters (500 milliliters) + 300 milliliters = 800 milliliters.
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 should be added to a beaker half filled with water t raise it's water level?
To raise the water level in the beaker, you should add more water to it. The amount of water added should be equal to the volume you want the water level to increase by.
What happened to the water in the beaker?
The water in the beaker evaporated or was poured out.

What instrument using for determination of concentration of salt water?
Measure out any volume of water in a pre-weighed beaker (or container...sigh*). Then bake the beaker in a warm oven until all the water evaporates and the beaker is dry. Reweigh the beaker . Subtract the original weight of the empty beaker from the new weight. You now have the weight of the salt present in your original amount of water ! NOTE: If you are using ocean water this may be imprecise due to other contaminants remaining in the beaker. AKA you are not JUST weighing salt at the end.

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.
Beaker X contains 50cm3 of marbles while Beaker Y contains 100cm3 of water. When all the water in Beaker Y is poured into Beaker X what is the volume of the water in Beaker X?
The volume of the water in Beaker X will be 100cm3, as you are not adding any more water to the equation (50X+100Y is not 150Y or X, but 50X+100Y) The total volume of matter in Beaker X will be 150cm3, and if the beaker is labelled, the volume measure will indicate 150cm3 due to the displacement of water. But as the answer to your question, the volume of water in Beaker X must be 100cm3 even though visual indicators will not show this due to the displacement of water by marbles
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.
How does is the temperature of beaker measure in water?
The temperature of a beaker is typically measured using a thermometer that is placed in the water inside the beaker. The thermometer will provide a reading of the water temperature, which indirectly reflects the temperature of the beaker as well.
The instruments scientist use to record the measurements?
beaker to measure the amount of water the weighing scale a ruler thermometer etc.
How much does a beaker weigh with 40ml of water?
The weight of the beaker with 40mL of water will depend on the density of the water and the material of the beaker. Water has a density of 1g/mL, so the weight can be calculated by multiplying the density by the volume. The weight of the beaker itself will need to be accounted for as well.
