What else can I help you with?
What is another name for a test tube?
another name for test tube is culture tube or sample tube
How high is 2 mL of water in a test tube?
It depends on what size test tube you are using.
What is contained in a clean dry test tube?
If a test tube is clean and dry, then there should be nothing in it.
How could you test if argon is a non metal?
You first get a bowl of tap water, get a test tube with the argon in it. Take out the cork screw out of the test tube. Get a splint put it over the test tube when you open it and it it pops that means it is a metal
Is test tube baby immoral?
It is subjective as to whether a test tube baby is immoral or not. Some religions feel that it is.
Did anything happen to the surface of the pyrex test tube in this flame?
Pyrex is resistant to thermal shock and can withstand high temperatures, so the surface of the Pyrex test tube likely did not change in the flame. It should remain unaffected under normal laboratory conditions.
Did anything happend to the surface of the pyrex test tube in this flame?
In a flame, the surface of a Pyrex test tube may become sooty or blackened due to carbon build-up. This is typically a result of incomplete combustion of the gas or other material being burned. Pyrex glass itself is resistant to high temperatures and is unlikely to melt or deform in a regular flame.
If a sample contained 1 gram of pure substance A and another test tube contained 4 grams of pure substance A how would the melting point differ and how would the experiment differ?
The melting point is independent of the quantity. What changes is the amount of heat which must be supplied.
What will happen if you heat few grains of clean sand in a test tube?
Try it and you'll find out !
What steps can you take to determine the melting point of a substance that sublimes before it melts?
In such cases the melting point determination must be performed in a sealed capillary tube to avoid loss of sample. This can be achieved by heating the open end of the capillary tube, and with tweezers forcing it shut.
What is a thiele tube is used to?
A Thiele tube is a simple device used in chemistry for measuring the melting or boiling points of substances. It consists of a capillary tube attached to a thermometer and is immersed in the substance being tested. Changes in temperature are observed to determine the melting or boiling point accurately.
Why can't we reuse a capillary tube to determine the melting point for a second time?
ur muff cabbage
Why do you use a new capillary tube for melting point determination each time?
It is not easy to be cleaned inside.
Never point the test tube towards your partner?
You can cause damage to them!
Whats the best method of heating fluid in a test tube is to point the flam directly at the bottom of the tube?
FALSE!!
What would a glass test tube cost?
That depends on the size, the type of glass, and if the test tube has an special features - such as threading at the top to allow a screw cap to be screwed on... With that said, a typical price for the test tubes you usually see is around $1/each for a 14 ml Pyrex test tube. I've seen really cheap ones for less than half that when bought in bulk and some specialty ones that were over $5/each.
Why do not point the test tube to anyone nor look into the test tube while it is being heated?
Because if the experiment being conducted in the test tube is explosive or very reactive then it can spit out stuff and this can be dangerous to your eyes or skin. so by pointing the test tube away then you won't harm anyone if anything spits out
