Why should use a glass rod when pouring a liquid into a narrow-mounted container?
Wiki User
∙ 7y ago
A glass rod should be used when pour liquid into a narrow mouthed container because of the adhesive force between the glass and the liquid. This will cause the liquid to run down the glass rod and into the narrow mouth without spills.

How much liquid volume is in a container of milk?
Milk comes in different sized containers. The volume should be clearly written on the label.
How do you measure the amount of liquid in a container?
Find another smaller container of known volume. Pour and see how many times you can fill it and add it up. Any final fraction should be fairly easy to guestimate
When measuring you do the measurement from the bottom of the meniscus?
You should always measure at the lowest part of the meniscus. The meniscus is a slight curvature at the top of a liquid in a container.
How would you verify the Archimedes principle for objects that are less dense than the liquid?
Two ways to do this: 1) Floating the less dense object on the more dense liquid. To verify the Archimedes principle you need to show that the mass of the liquid displaced by the less dense object is equal to the mass of the less dense object. To do this you need to have a way to determine the mass of the displaced liquid. If the liquid is in a container filled to the brim, then when you place the less dense object in it, the displaced liquid will spill out over the edges of the container. If you can collect and weight that liquid, then you can compare its weight to the weight of the less dense object - they should match. Alternatively, you can find a way to measure the volume of the displaced liquid and calculate the mass from the volume and density of the displaced liquid. 2) Immerse the object completely in the liquid and measure the force required to keep it submerged. This one is more complicated and difficult to execute and measure. The force required to keep the less dense object submerged should be the difference between the weight of the object (when it is not in the liquid) and the weight of the displaced liquid.
Liquid exerts pressure on container than why do they are still if it is exerting pressure than it should move.?
Exactly right! As long as there's a 'net' force ... that means anything left over that'snot zero after all the forces present are added up.So let's not forget the Newton's law that says that there's an equal and oppositereaction for every action.In this particular case, the action is the force that the liquid exerts on the container,and the reaction is an equal and opposite force that the container exerts on the liquid.The two forces are equal and opposite, so they add up to zero. There's no net forcewhere they meet, so nothing accelerates.If the force of the liquid is so great that the material of the container can't providean equal, opposite reaction, then the material of the container falls apart, and theliquid accelerates all over the place.
When pouring a liquid why should the neck of the bottle touch the rim of the receiving vessel?
Touching one container opening to the other container's opening as the bottle is tipped up to start the flow of the liquid will (1) steady the "aim" and delivery rate of the liquid from the bottle; and (2) the connection will take advantage of the liquid's surface tension to promote smooth and controlled flow. The use of a stirring rod from one container to another will produce similar results.
How do you use a hand pump siphon?
One tube from the hand pump should be placed inside of the liquid that is to be siphoned. The other tube should be placed in an empty bucket or other container. The pump should then be squeezed and released to move the liquid from the container that it is currently in into the other empty container.
What container should be used to store flammable liquid?
When storing a flammable liquid, select a container that is stable (unlikely to tip over), able to be tightly closed (to prevent or control evaporation), and that is made out of a material that is chemically compatible with the flammable liquid.
How can you purposely grow mold on food for an experiment?
You can grow it by pouring water on a piece of bread. Then stick the piece of bread in a tupperware container for a few days. Then you should have bread mold. Hope this helps
Should you wrap soup for take out?
Soup being a liquid can not be "wrapped", it needs to be placed in a container, not paper or it will simply leak out.

Why should you never pour hot liquids into a cold drinking glasss?
you can if you put a spoon it the glass first before pouring in the hot liquid, otherwise the glass might crack

How do you check the coolant level?
there should be a clear white juglike thing that says coolant on the lid... look at the liquid level on the container
What would be the easy way to scale a keg beer liquid content for inventory reasons?
Weigh the keg. The tare weight should be on the container, subtract the tare and convert the weight of the contents to liquid.
The mass of an empty container is 88.3 g The mass of the container and a liquid with a density of 0.758 gmL is 150 g What is the volume rm mL of the liquid in the container?
First, subtract the weight of the empty container from the total, so you're leftwith just the weight of the liquid.150 - 88.3 = 61.7 gThen, divide the remaining weight by the density of the liquid to find the volume.61.7 grams/0.758 grams per ml = 81.398416886543535620052770448549 mlSince the numerator and denominator of the fraction have 3 significant digitseach, nothing past the 3rd significant digit in the quotient can be trusted. Soit should be rounded to 81.4 ml.
