Why to point the open end of a test tube or flask away from yourself and others while heating never heat a closed container is important?

Suppose the liquid in the tube were to boil. In the first case, it might boil out of the tube and splash over someone; in the second case, the pressure will go up dramatically and could cause the container to explode.

What is the answer A closed container of air and 5 g of tin metal have a total mass of 765 g. After heating the container and its contents have the same mass as before (765 g). When the container i?
This is the law of mass conservation. If the external surface of the container react with air the law is not applicable, a new compound is formed.
Will water evaporate in a closed container like a closed pipe?
Water can be evaporated from a sealed container.
What can handle more pressure a small closed container or a large closed container if the amount of liquid placed in it is the same?
small container
Why Heating a gas in a closed container will increase its pressure?
The gas molecules gain energy from the heat and so they speed up, causing the pressure to increase.
What will cause a decrease in pressure in a closed container?
A decrease will occur if the lid of the container is opened.
How does heating a gas in a rigid container change pressure?
Heating a gas in a closed container would increase it's pressure. This would happen because when you heat the gas, the particles' kinetic energy increases, making them move faster, and more. They will hit the sides of the container and create pressure.

Why is it important to seal a container when growing bacteria?
A container that has growing bacteria must be closed and/or sealed to prevent contamination by other bacteria.

Is an open fire or closed fire best for heating a house?
The answer is that a closed fire is best for heating a house.
How is the gas pressure produced in a closed closed container of gas?
the particles of gas bouncing into the walls of the container.
Why cant animals survive in closed container without?
They can't live in a closed container because there is no oxygen.
In a closed radiant floor heating system how do you get hot water to flow out of the top of your hot water tank?
Playing with closed hot water heating systems is dangerous and can result in serious personal, and property damage.If you are determined to do the work yourself, you need to study the subject more.
What will cause a decrease in a gas pressure in closed container?
Lowering the temperature will cause a decrease in gas pressure in a closed container.
Should containers be closed when microwaving?
No, any container that is closed will develop pressure when heated. The water to steam ratio is ~1603 : 1. This means that 1 cubic centimeter of water expands to about 1603 cubic centimeters of steam. Any container that is tightly closed won't be if it is heated enough as that steam WILL find a way to escape often explosively. It is best to leave a small opening when heating anything.
