When water in a glass tube is heated the level of water in the tube?
rises because the water expands when heated, causing an increase in volume which leads to a higher level in the tube.
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
Why do tube lights do not get heated?
because tube lights are made of glasses. and when its break down then nobody gets heares
Why should you not look over the mouth of the test tube being heated nor point it at someone?
This is a huge safety concern. When the reactants are being heated, a hotspot could cause an explosive bubble to form which may spray out. If someone is in that path, they could be burned or poisoned.
What happens when magnesium nitrate is heated in a an ignition tube?
a reddish brown gas is formed. Water droplets are formed on the sides of the tube.
What instruments hold test tube being heated?
A retort and clamp or tongs.
Why the thiele tube is shaped the way it is?
The thiele tube allows convection currents in the oil when it is heated meaning there is fairly uniform distribution of temperature.
Should you hold a test tube while being heated?
no, you'll burn yourself
What brown coloured gas evolveed when lead nitrate crystals are heated in adry test tube?
The brown colored gas that evolves when lead nitrate crystals are heated in a dry test tube is nitrogen dioxide.
What happens if ammonium chloride is heated in a test-tube with a long neck?
When ammonium chloride is heated in a test-tube with a long neck, it will sublimate directly from a solid to a gas without melting. The gas will then travel up the long neck of the test tube and may condense back into solid form upon cooling, forming a white crystalline residue at the top of the tube.
What do you call the purple gas that fills the test tube when a few crystal of iodine is being heated inside a test tube?
This is also iodine, as a gas.
What happens to air particles when heated in a test tube?
When air particles in a test tube are heated, they gain kinetic energy and move more rapidly. This increase in movement causes the particles to collide with each other and the walls of the test tube more frequently and with greater force, leading to an increase in pressure if the volume of the test tube remains constant. As a result, the temperature and pressure of the air inside the test tube rise.
