What happen if heat is applied at the bottom of a test tube containing liquid on it?
You should never point the open end of the test tube when heating liquids toward yourself or others for your own safety. Liquids inside the test tube when heating may release some gases and might affect someone when you point the open end of the test tube to them. when heating the test tubes, position it diagonally and move it slowly sidewards so we can prevent cracking or breaking of the test tubes if directly positioned on fire.

What will happen to the powdered sulfur when heat was applied?
When heat is applied to powdered sulfur, it will melt and eventually vaporize. This process is called sublimation, where a solid substance bypasses the liquid phase and turns directly into a gas.
Where in a liquid does boiling happen?
Boiling in a liquid occurs throughout the entire volume of the liquid, as the heat energy applied causes the liquid to reach its boiling point temperature, at which the liquid's vapor pressure equals the external pressure. This results in bubbles of vapor forming within the liquid and rising to the surface.
The image below shows a jar containing four different liquids, each a different color The liquids do not mix, so the colors remain separate Which of these liquids has a density greater than that of?
red clear blue
What happen when heat is applied to an airtight vaporizer?
When heat is applied to an airtight vaporizer, it causes the substance inside (such as liquid or dry herbs) to reach its boiling point and vaporize into a gas without combustion. This vapor can then be inhaled for the desired effects without the harmful byproducts associated with smoking.
Why was it important not to let the thermometer rest on the bottom of the breaker?
It is important not to let the thermometer rest on the bottom of the beaker because the bottom can be heated unevenly leading to inaccurate temperature readings. Placing the thermometer in the liquid away from the bottom ensures a more accurate measurement of the liquid's temperature.
What happen after the sugar solution evaporated?
The Sugar will be left at the bottom and the liquid will be gone.
Why doesn't ketchup come out of the bottle when you tap on it?
Because it is a non-newtonian liquid and that means when force is applied it turns from a solid to a liquid or vice versa. In this situation it goes from solid to liquid. So you only turn the bottom to liquid. Tap on the neck. Some should come out.

Was agent orange a gas or liquid?
Agent Orange was a herbicide blend containing two chemicals known as 2,4-D and 2,4,5-T. It was primarily used as a liquid, which was sprayed from aircraft and other devices during the Vietnam War to defoliate forests and destroy crops.
What does sanitizing mean?
A liquid containing chemicals that sanitizes (cleans) whatever it's applied to. e.g: liquid soap dispenser
What does sanitizing solution mean?
A sanitizing solution is a liquid or spray that is used to reduce the number of germs, viruses, and bacteria on surfaces. It is commonly used in cleaning practices to promote a healthy and hygienic environment.
A liquid containing a homogeneous mixture?
solution
Why do glasses containing cold liquids sweat in warm weather glasses containing alcoholic drinks form frost on the outside How can this happen?
This is called condensation. The moisture in the air condenses into liquid, when it's near a source colder than the surrounding air.
What will dissolve adhesives containing xylenes?
Xylene liquid will.
What do you call Product containing no liquid at all?
aneroid
The pressure at the bottom of a barrel filled with liquid does NOT depend on the?
The pressure at the bottom of a barrel filled with liquid does not depend on the shape or size of the barrel. It depends only on the depth of the liquid and the density of the liquid.
What would happen if you have 2 liquids with different densities in the same container?
The liquid with higher density will settle at the bottom, while the one with lower density will float on top due to the principle of buoyancy. The liquids will not mix and will form distinct layers based on their densities.
