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
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.
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
Which graduated cylinder would be the best one to use to measure exactly 15ml of water?
beaker
The temperature of true water is in a beaker is 25 c after adding a piece of magnesium to the water the temperature increase is this an exothermic or an endo thermetic?
exothermic ? because energy released
Which laboratory tools are used to measure the temperature of water in a beaker?
It's got to do with science
Does beaker measure water?
yes
Is there a method to link the mass of water and the temperature rise?
1. Measure out 1 kg of cold water into a large beaker. 2. Measure and record the initial temperature of the water. 3. Put an immersion heater into the water and switch on for a fixed period of time, eg 10 minutes. 4. Measure and record the temperature at the end. 5. Work out the change in temperature. 6. Repeat for several other masses of water.

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 would you carry out a test on 3 different lining materials?
have three beakers filled with water all at the same starting temperature. wrap a different material on each beaker and leave for 15 minutes. measure the temperature of the water. water with the highest temperature is the best insulator
What is temperature in physics?
Temperature is a measure of the concentration of thermal energy. Consider a lit match and a beaker of room temperature water. The water will have more thermal energy (due to water's high specific heat capacity) than the flame, but the thermal energy of the flame is more concentrated.
What is the tool to measure volume using water displacement?
A beaker is used to measure volume using water displacement.
What is a a beaker used for?
To measure volume
How do you measure weight and volume of water not quite filling a 50ml beaker?
It is necessary to know the mass of the empty beaker.
