Do all ammonium compounds sublime?
No, not all ammonium compounds sublime. The ability of an ammonium compound to sublime depends on its specific chemical properties, such as its volatility and stability under heating. Some ammonium compounds do sublime, like ammonium chloride, but others may decompose or melt before sublimation can occur.
Can solid carbondioxide sublime on heating?
Yes, solid carbon dioxide, also known as dry ice, can sublime directly from a solid to a gas when heated. This means it skips the liquid phase and turns directly into carbon dioxide gas. Sublimation occurs because the pressure and temperature conditions allow the solid to transition directly into a gas.
Why is heating a candle a chemical change?
Heating a candle causes its wax to melt and burn, which involves a chemical reaction where the wax molecules are broken down and combine with oxygen in the air to produce heat, light, water vapor, and carbon dioxide. This transformation of wax into different compounds is a chemical change, as the composition of the candle wax is altered irreversibly during the process.
How do you melt parrafin wax?
To melt paraffin wax, use a double boiler or a microwave-safe container. Place the wax in the container and heat slowly until it reaches approximately 160-180°F (71-82°C), stirring occasionally. Make sure to follow all safety precautions when working with hot wax, as it can be flammable.
Why does candle wax melt on heating?
Candle wax is made of hydrocarbons, which have high melting points. When heated, the heat energy breaks the intermolecular forces holding the wax molecules together, causing them to move more freely and transition from a solid to a liquid state. This is why candle wax melts when heated.
Does sodium chloride sublime on heating?
Sodium chloride can be melted or boiled but not sublime.
Why is the wax become solvent?
When wax melts by heating it up, it becomes liquid.
Do all ammonium compounds sublime?
No, not all ammonium compounds sublime. The ability of an ammonium compound to sublime depends on its specific chemical properties, such as its volatility and stability under heating. Some ammonium compounds do sublime, like ammonium chloride, but others may decompose or melt before sublimation can occur.
What type of process occurs when solidified wax is converted to liquid wax on heating?
The process that occurs when solidified wax is converted to liquid wax on heating is called melting. Melting is a physical change in which the solid wax absorbs heat energy, causing the molecules to vibrate and break free from their fixed positions, transforming the wax from a solid to a liquid state.
Why sublime substance change directly from solid to gas on heating?
Because the entropy is negative making it spontaneous.
Can solid carbondioxide sublime on heating?
Yes, solid carbon dioxide, also known as dry ice, can sublime directly from a solid to a gas when heated. This means it skips the liquid phase and turns directly into carbon dioxide gas. Sublimation occurs because the pressure and temperature conditions allow the solid to transition directly into a gas.
How do I remove wax from heating vent?
Use moderate heat such as a blow dryer. Be careful not to get the wax hot enough to burn.
Does sodium chloride sublime upon heating?
Yes. It will become sublime of a heat consisting of a large energy and very high temperature. It is not noticable by naked eyes as it becomes smaller & smaller at last it vapourises. Evaporation of salt can be noticed many times in nature when a rainfall ocurrs its droplets are salty in taste.

What is a wax pot?
A wax pot is a device used in beauty salons and spas to melt wax for hair removal treatments. It typically consists of a heating element and a removable pot for holding the wax. The wax is heated to a specific temperature to make it suitable for application on the skin.

What tools are used for batik?
Batik is done with the cloth being "batiked," wax that is melted in a pot or other heating device, and either a brush or a tjanting to spread the wax
