It melts.
This is assuming you're heating it in the absence of oxygen, or at least in such a way that it doesn't burn.

What happens when you heat NaHC03 in a test tube?
It partially decomposes to Na2CO3, CO2 and H2O according to: 2NaHCO3 --> Na2CO3 + CO2 + H2O
What happens if you use a luminous flame to boil water in a test tube?
Carbon is settled on the test tube.
What happens when you thrust a glowing bamboo stick inside the test tube?
If only oxygen is in the test tube, it may burst into flame.
Why don't you heat a test tube continuously?
To avoid dangerous tension in the glass.
What is the material used to hold test tubes?
A boiling tube is used for boiling a liquid in
What happens if the mixture of iron and sulfur is heated in a test tube?
it makes it biger
How do you heat a small amount a alcohol in a test tube?
heat the test tube in inclined position..alcohol is a hydrocarbon
Why do we use test tube?
we use test tube to hold chemicals and heat and chemicals.
What is the proper way to heat a liquid in a test tube?
the proper way to heat a liquid in a test tube is by putting it in open flame.
What happens when you heat NaHC03 in a test tube?
It partially decomposes to Na2CO3, CO2 and H2O according to: 2NaHCO3 --> Na2CO3 + CO2 + H2O
What happens when you place a lighted match near the mouth of the test tube?
It depends on what is inside the test tube. If the test tube is empty nothing will happen, if there is petrol in the test tube the petrol will ignite.
What happens if you use a luminous flame to boil water in a test tube?
Carbon is settled on the test tube.
Why do we heat the test tube in a water bath not directly over a flame?
IN Physics wards:Why do we heat test tube in a water bath and not directly over a flame?
In terms of heat conservation how can heat be lost from a hot test tube containing wax?
Heat is transferred by three methods; Convection, conduction or radiation. If the test tube is touching anything (such as the stand or a table) then heat can be lost through conduction; the hot test tube transfers heat to the stand. You can reduce this heat loss by using a material such as wood that does not conduct heat well. The air around the test tube will be heated, and the hot air rises away, allowing cold air to flow around the test tube. The new cold air becomes heated, and rises away and.... This is called convection. Even in a vacuum, the heat of the test tube will be lost through radiation, as the heat of the test tube is transferred to nearby objects. If you put your hand near the test tube, you can feel the heat even without touching it. This is how the heat from the Sun reaches the Earth, even though we're not touching the sun and the 93 million miles of space between us and it is a pretty good vacuum.

What happens to the falme when th burning splint is put into the mouth of the test tube with the test tube of solid calcium carbonate in it and then heated?
The burning splint is extinguished by the carbon dioxide given off from the calcium carbonate. CaCO3 --heat--> CaO + CO2 ==================================================
What happens when you thrust a glowing bamboo stick inside the test tube?
If only oxygen is in the test tube, it may burst into flame.
