What does a chemical property give a substance the ability to do?
A chemical property is the properties exhibited by a material in a chemical reaction. This gives a substance the ability to have a chemical identity and is also used in building chemical classifications. The properties can be used in identifying a substance that is unknown or to separate substances. The property also helps in providing information on the application of a substance.
Where does lost energy in a rheostat go?
It is lost in heating the resistive material of the rheostat.
When you are heating materials in a test tube what is very important about the mouth of the test tube?
The most important aspect of heating liquids in a test tube is to never look directly into the mouth of the test tube, as liquid may spurt out and come into contact with your eyes or face. However, if you are wearing plastic safety glasses, the substance may not harm you, depending on the type of substance you are heating.
Who use solar energy and for what purpose?
Solar Energy is used for heating buildings and water, and produces electricity for buildings, also.
Temperature is the what of the average kinetic energy of the molecules in a substance?
The average energy is increased by heating.
Why don't wood melt on heating?
wood doesn't melt on heating because while heating the compound required to change that substance into liquid gets evaporated quickly when we start heating.
Does the rate of heating equal to the rate of cooling of a substance?
No, the rate of heating and the rate of cooling of a substance are not necessarily equal. The rate of heating refers to how quickly a substance gains heat energy, while the rate of cooling refers to how quickly a substance loses heat energy. These rates can be different depending on factors like the material of the substance, the temperature gradient, and the presence of insulation.
Was there a new substance formed after heating the iron sulfur mixture?
Yes, a new substance, iron sulfide, was formed after heating the iron-sulfur mixture. Iron sulfide is a chemical compound that results from the combination of iron and sulfur atoms during the heating process.
A solid substance left after heating coal or petrol?
The solid substance left after heating coal or petrol is known as coke. It is a carbon-rich material that is commonly used as a fuel and in industrial processes such as steelmaking.
Heating a chemical compound produces elements?
Heating a chemical compound can cause it to undergo decomposition, leading to the release of elements present in the compound. This process is known as thermal decomposition and is often used to extract elements from compounds in laboratory and industrial settings.
A substance X on heating gives B and C What is X a compound or a mixture?
It may be a compound as CaCO3 which on heating gives CaO and CO2, it may be a mixture as mixture of Naphthalene and sand which on heating gives naphthalene and sand.
Why heating enzymes usually produces a faster rate of reaction?
Why heating enzymes usually produces a faster rate of reaction?
What heating methods will fail to heat a material that has no moisture content?
Heating methods that rely on the presence of moisture content in a material, such as microwave heating or steam heating, will be less effective on a material with no moisture content. In that case, methods like convection heating or radiation heating would be more suitable for heating the dry material.
What is the equation to use to find mass of x lost by hydrate?
Weight of hydrated substance - weight of same material after desiccation.
When heating a substance what happens?
Heating a substance can result in a chemical reaction, which usually results in a simple combustion reaction. This is because Oxygen, or O2, is added to the substance, which can dramatically alter the substance.
What happens to the mixture of iron fillings and sulphur powder after heating?
That produces a strongly exothermic reaction that results in the production of a grey substance, an iron sulphide. Please see the link.
What is the process of molten material?
The process of molten material involves heating a solid substance to its melting point, causing it to turn into a liquid state. This can occur through various methods such as heating in a furnace or using a torch. Once in a molten state, the material can be manipulated or molded into different shapes before it solidifies again upon cooling.
