Is the surface of water flat?
Technically, No. Water in a glass (or other vessel) has a curved surface known as a meniscus. A large body of water (like an ocean) actually follows the curve of the earth. So the surface of the water is a curve or section of a sphere.
Explain why the surface of water in a container is not flat but curved?
Surface tension.
What is the maximum depth a water spill will be on a flat surface?
Any, depending on the volume of water spilt and the area of the flat surface. The specific height is also constrained by the surface tension of the water, the atmospheric pressure above it, and the gravity below it.
Does the surface of mars have long channels from water flow?
They believe that it is from water flow.
Why will a vacuum pump not work in a well that is more than 10 m deep?
The water is pumped upwards by the atmospheric pressure acting on the surface of the water in the well. That is only strong enough to support a column of water that is 10m tall.The water is pumped upwards by the atmospheric pressure acting on the surface of the water in the well.

Why can you observe water droplets on the surface of a chilled bottle?
You can observe water droplets on the surface of a chilled bottle because the temperature of the atmosphere is a different temperature to that of the temperature in the chilled bottle.
Which instrument is used in submarines to observe the surface of water?
A Periscope or Radar
How far from the edge of the table do you place your plate?
There is no set rule for the placement of a dinner plate, but a good host will set a salad or bread/roll plate to the top left and a soup bowl and plate can be placed upon the top of the dinner plate if desired. A glass of water and/or wine can be placed at the top right.
How can i repair surface of mild steel plate with putty to fill or plain surface that looks like iron?
Please mention the particular application of MS plate.....(sea water,DM water ,)
Why were scientists surpised to observe recently formed liquid water channels on mars?
Mars is too cold for liquid water to flow on the planet surface
Why does the water kept in a plate evaporate faster as compared to that kept in a test tube?
The water surface able to be evaporated is greater.
Why must we use sterile techniques to incubate agar plates?
Because if the plates are wet you will not get individual colonies, instead you will get a film of bacteria growing in the water film on the surface of the plate. This can ruin a selection for transformants as the antibiotic will not be present in the water film on the surface of the plate.
Can MDF observe water?
no, MDF cannot observe water
Are under water and land surface mountains formed bt the same plate movement?
No, because if one plate is moving down then it would be underwater mountain, if the plate moved upward the it would be land mountain
If water spreads out on a glass plate is this an example or cohesive or adhesive force?
Both, the water molecules are cohesive to each other, and the outer water molecules are adhesive to the table surface.
Why is it important to keep the temperature and the amount of water the same when testing surface area?
The temperature and the amount of water need to be kept the same so that the only variable that changes is surface area. If you allow the temperature and/or the amount of water to change too, you will not know which variable is causing the changes that you observe.
What is the name of a smooth surface that reflects an image of what is in front of it?
The reflective surface is a mirror. It can be highly polished metal or chromed, the surface of a calm area of water, or a flat glass plate with a silvered back and a protective coating.
