The glass at the bottom is not of uniform thickness and not of optical quality. The rays of light from the objects that you are looking at are, therefore diffracted and absorbed in different ways. This causes the distortions.
This is called refraction. The rays of light bend.
The shape of the glass, and the refraction of the light in the water act as a magnifying lens.
Non Ablative bottom paint is a paint film that does not wear down its thickness as it moves through the water. Ablative paint wears down its paint thickness through friction with water. A perfect analogy would be like a bar of soap wears down in time through friction of rubbing on your skin. Non ablatives do not wear down.
YES!
its the bottom of your digestive system. ;)
You need a diamond core bit for the size hole you want, fasten the bottle in a drill press securely but carefully, its important you keep the bottle from moving, pick the area you want the hole and build a dam with clay to hold water, once everything is fasten, water in the dam, have the speed of the drill press at around 500rpm, now apply light pressure for 3 to 5 seconds, lift the bit slightly allowing the water to rinse the bit and apply light pressure again for another 3 to 5 seconds, continue these steps until you cut through the bottom. TIP: "DO NOT" get impatience and try to cut faster, you will only wear out or ruin the bit. If you follow these steps your core bit will last you through many-many holes. (I caution you against using a hand drill)
Woki Toki is not a item. Walkie Talkies can be made from two cups and running a piece of yarn through each cups bottom and tying it.
Water can be condensed on the bottom of the glass cover.
Decreases!
It is important to let the sand settle at the bottom of your beaker so that the sand is separated from the liquid.
to get an accurate reading of the liquid inside the beaker, the thermometer should not rest on the bottom of the beaker.
Luminous flame produce deposit on the bottom of the beaker because when the beaker is near the flame, it limits the amount of oxygen for the methane, thus, the deposit (which is Carbon), is produced.
Inform their teacher and then throw the beaker in the broken glass
hotter
The sides or bottom of the beaker will likely be at a significantly different temperature than the liquid.
The bottom and sides of the beaker will be hotter than the liquid inside.
They will diffuse equally throughout the beaker
The most efficient, and safe, place for a beaker to be heated is above the flame. Have the beaker held up by the proper metal stand and have it held so that the flame is grazing the bottom of the beaker. Be careful though, the flame should only graze the bottom of the beaker so that the chemical doesn't heat up too quickly.
