What happens when oil is poured in to u- bend test tube of water?
When oil is poured into a u-tube test tube of water, the oil will separate from the water due to their difference in density. The oil, being less dense, will float on top of the water, creating two distinct layers. This is because oil is hydrophobic and does not mix with water.
How do you draw a test tube?
To draw a simple test tube, use a long, narrow cylinder with a rounded bottom and an open top. Add a small line near the top to indicate the opening of the test tube. You can also include liquid inside to make it look more realistic.
What does test tube rack looks like?
A test tube rack is typically a rectangular or circular stand with holes or slots designed to hold test tubes in an upright position. They can be made of various materials such as plastic, wood, or metal, and may come in different colors or sizes depending on the number of test tubes they are designed to hold.
Why do glaciers form U-shaped valleys rather than V-shaped valleys?
Glaciers form U-shaped valleys due to their ability to erode and transport large amounts of rock and sediment. As glaciers move downhill, they carve and widen the valley floor, creating a broad and deep U-shaped profile. In contrast, rivers mainly erode the valley through the process of hydraulic action, which tends to create narrower and steeper V-shaped valleys.
How do you smell a substance in a test tube?
Make ur hands move back and foth in a wifting motion so u can get the smell to come to your nose. dont get close to the chemical. Just make ur hand make a motion that makes the air and the odor of chemical to come to ur nose
What is a hard glass test tube?
A test tube, also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clearplastic tubing, open at the top, usually with a rounded U-shaped bottom. A large test tube designed specifically for boiling liquids is called a boiling tube.
What is test tubes and how is it use?
A test tube, also known as a culture tube, is a piece of laboratory glassware composed of a finger-like length of glass tubing, open at the top, with a rounded U-shaped bottom. Often, the top features a flared lip. This is to aid pouring of a liquid from the test tube to a beaker. A distinction between test tube and culture tube is often made, calling a tube with a lip a test tube and one without a lip a culture tube

What is the function of a J-tube and a U-tube?
A J-tube is a type of gastrostomy feeding tube inserted into the jejunum to deliver nutrition directly into the small intestine. A U-tube is a type of manometer used in physics and fluid mechanics to measure pressure differences between two points in a fluid system.
What is the definition of U-tube manometer?
A U-tube manometer is a device used to measure pressure differences in a system. It consists of a U-shaped tube partially filled with a liquid, such as mercury or water, and is connected to the system where pressure needs to be measured. The height difference of the liquid levels in the two arms of the U-tube indicates the pressure difference.

How do you measure exactly 60g of salt in a test tube?
First we measure the test tube on the weight machine and note it . let the wieght be 'a' grams. After that keep putting the salt in the tube until the weight of the test tube ,with salt in it, is = (a + 60) grams . If u accomplish this that means that the salt in the tube is exactly of 60 grams :) .
