How do convention currents move?
Heated from the bottom, the warmer substance will slowly rise to the top while the cooler substance at the top falls to the bottom to be heated again. Look at a lava lamp. That is all about convection currents.
What type of substance is heated by radiation?
Any substance that absorbs the radiation is heated by it.
How do you make an improvised evaporating dish?
To make an improvised evaporating dish, you can use a clean, shallow container like a ceramic or glass dish. Ensure that it is heat-resistant and has a flat bottom to allow for even heat distribution during the evaporation process. Avoid using containers made of plastic or materials that may release harmful chemicals when heated.
What is the name of the substance created when zinc is heated with sulphur?
The substance created when zinc is heated with sulphur is zinc sulfide.
What is the symbol for mass of the substance being heated?
The symbol for mass of the substance being heated is typically represented by the letter "m" in physics and chemistry equations.
What is the black substance on the bottom of the evaporating dish after it has been heated on a Bunsen burner?
The black substance is likely to be the residue of the substance that was heated in the evaporating dish. This residue is left behind after the solvent or liquid has evaporated, and can be carbon or other impurities from the original substance. It is important to clean the evaporating dish thoroughly to remove the residue before its next use.
A sample of copper powder is heated in an evaporating dish using a Bunsen burner. If the mass of the powder in the evaporating dish increases after heating this indicates that?
the copper must have combined with another substance.

Can an evaporating dish be heated on a hot plate?
Yes, an evaporating dish can be heated on a hot plate to facilitate the evaporation of a solution. However, it is important to control the temperature to avoid overheating or damaging the dish. use a heat-resistant container if heating directly on the hot plate.
What is the name of the black solid which collects on the outside of an evaporating basin when it is heated by a yellow Bunsen flame?
The black solid that collects on the outside of an evaporating basin when heated by a yellow Bunsen flame is likely soot. Soot is a carbonaceous substance formed from incomplete combustion of carbon-containing materials.
What type of substance is heated by radiation?
Any substance that absorbs the radiation is heated by it.
Why can't we heat the evaporating dish with direct fire?
Heating an evaporating dish directly with fire can lead to uneven heating, causing the dish to crack or break. It can also result in thermal gradients that affect the evaporation process and may cause the substance being heated to burn or decompose. Using a water bath or heating mantle provides more controlled and uniform heating for evaporating liquids.
