A hot beaker warms the air around it, which causes it to rise. For very sensitive balances, the updraft produced can reduce the measured weight.

Is beaker used in measuring exactly 15 g salt?
You need an analytical balance and a small beaker.
What is the mass of the beaker and fluid on the triple beam balance?
To determine the mass of the beaker and fluid on a triple beam balance, you would first place the beaker filled with the fluid on the balance. Then, you adjust the sliders on the beams until the balance is level, indicating that the total mass is equal to the sum of the beaker's mass and the fluid's mass. The reading on the balance will give you the combined mass of both the beaker and the fluid. If you need the mass of each separately, you can weigh the empty beaker first and then subtract that mass from the total.
What is the mass of a 400ml beaker?
Approximately 1 gram/millilitre for the water, but not all small beakers of water have the same mass. In fact, it's much more likely the masses differ than are the same. Are you trying to fake a lab exercise or is this just a silly question?
What is the mass of 250 mL beaker filled with 100 mL of water?
Well, darling, a 250 mL beaker filled with 100 mL of water would have a mass of approximately 100 grams. Water has a density of 1 g/mL, so 100 mL would weigh 100 grams. The beaker itself doesn't add any weight, unless you're counting the weight of your expectations.
What do you check before using a triple beam balance?
to measure the mass of objects
Why you need to cool the sample first before you weigh it?
The reason you heat the test tube before weighing it is because of the residual moisture on the test tube itself. The weight of the glass itself will not change, but if there is moisture inside the tube, it could distort your readings. Therefore, you heat the test tube to evaporate any moisture remaining in the test tube to get an accurate weight measurement.
Do beans need to cool before refrigeration?
No
How long does it take for cookies to cool before they can be eaten?
Cookies typically need to cool for about 10-15 minutes before they can be eaten.
Is beaker used in measuring exactly 15 g salt?
You need an analytical balance and a small beaker.
How long does bread need to cool before it is ready to be sliced and served?
Bread typically needs to cool for about 30 minutes before it is ready to be sliced and served.
Do chinchillas need to stay cool at all times of the day?
Yes you need to freeze them before baking.
What does it mean to zero an electronic balance?
Usually you add a container to the balance then zero it. Then when you add something to the container e.g. a liquid or solid then when you place the container back on the balance the reading shows you how much you have added. Saves having to work out how much you added by weighing the container, weighing the container plus contents and then subtracting. Removes one possible source of error i.e. incorrect subtraction of values. Also faster/easier when trying to measure out a specific amount of a substance.
What tools will you need to boil water?
hot plate and a beaker
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.
Why is it important to determine the rest point of the triple beam balance before using it?
You need to set the balance to zero before using it because it affects the accuracy of the measurement. Ideally, you should set the balance to zero before each weighing.
Design uc based weighing machine using load cell to measure 20kg?
to design weighing machine we need tcfgx
What is the compound deposited on the inside of the beaker?
The compound deposited on the inside of the beaker is likely a precipitate formed from a chemical reaction that took place in the beaker. It could be a solid formed from the mixing of two solutions that reacted with each other. Further analysis would be needed to determine the specific compound.
