What are the precautions while heating alcohol?
1. Never heat alcohol directly on naked flame 2. you should take a beaker with boiled water in it and then place the alcohol with the test tube in it 3. you should wear goggles while heating alcohol. 4. never smell the alcohol directly after heating
When does the volume of wax increase when it is heated while that of water reduces?
On heating water from O0c to 4oc the volume of water decreases while that of wax increases.
Why water bath must be used while heating ethanol and acetone?
A water bath must be used while heating ethanol and acetone because the temperatures at which they can be heated might break the container they are heated in. Some metals are also heated this way.
What is the steps to use a beaker?
A beaker the the fundamental holding device in chemistry labs, at least in the ones I've been in. The use of a beaker is pretty self explanatory, place fluid within beaker, remove by pouring. But there are certain procedures that I've learned in chemistry labs, first, when pouring from a beaker, a stirring rod place on top of the beaker over the lip of the beaker prevents over flowing since the rod guides the fluid while pouring. Another thing is a beaker is never, never used over a Bunsen burner, really really bad idea, beakers are usually heated by hot plates. And of course handle any glass wear with care, and use tongs to handle hot beakers. Clean up with beakers is just basically soap and water, and most beakers can be washed in a dish washer, just don't wash chemistry beakers with the one you use for cookware.
While heating a solution in a beaker what is the appropriate safety equipment to have on the bench?

What happens when you put water in a beaker for a while and its gone?
It evaporated.
Beaker X contains 50cm3 of marbles while Beaker Y contains 100cm3 of water. When all the water in Beaker Y is poured into Beaker X what is the volume of the water in Beaker X?
The volume of the water in Beaker X will be 100cm3, as you are not adding any more water to the equation (50X+100Y is not 150Y or X, but 50X+100Y) The total volume of matter in Beaker X will be 150cm3, and if the beaker is labelled, the volume measure will indicate 150cm3 due to the displacement of water. But as the answer to your question, the volume of water in Beaker X must be 100cm3 even though visual indicators will not show this due to the displacement of water by marbles
Does water lose mass while heated?
no
What happends to the water when heat is applied to the beaker?
If you left water in an open container for several days in summer, the water would eventually evaporate and there would be less water than you put before but if you put in in winter, the water would eventually freeze.

Why is air important to cheetahs?
Air is important to cheetahs because they will get over heated while running and dry out. ummm.... they also need to breathe?

How much does a 150 ml beaker weigh in grams?
How much a beaker weighs depends on the size of the beaker and the thickness of the glass. A small beaker might weigh a few ounces while a large beaker will weigh several times that.
Does olivine form to anything when heated?
can heat form while heated
How do you separate sand from the salt?
Put the sand and salt mixture into a beaker of water. Put more water or raise the temperature of the water until the salt completely disappears. Pour everything in the beaker onto a piece of filter paper. The sand will stay on the filter paper while the water and salt solution will pass through the filter paper. To obtain the sale, simply boil the water and the remaining solid after all the water boiled is salt.
