As an object is heated, the rate of increase in temperature is proportional to the rate of heat added. The proportionality is called the heat capacity. Because the heat capacity is actually a function of temperature in real materials, the total amount of energy added will be equal to the integral of the heat capacity function over the interval from the initial temperature to the final temperature. If you just assume an average heat capacity over the temperature range, then the rise in temperature will be exactly proportional to the amount of heat added.
What else can I help you with?
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.
Substance left after heating coal or petrol?
The substance left after heating coal is coal ash. The substance left after heating petrol is a residue called coke. Both of these byproducts are typically composed of carbon and other elements.
What do we call substance which changes readily into vapour without heating?
A substance that changes readily into vapor without heating is called a volatile substance. Examples include alcohol and acetone.
What is a solid substance left after heating coal or petrol?
The solid substance left after heating coal is called coal ash, while the residue left after heating petrol is known as petroleum coke. These solid substances are byproducts of the heating process and can vary in composition depending on how the coal or petrol was processed.
Do the particles of a substance move faster or slower as the substance?
With the help of heating the movement is faster.
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.
Heating curve illustrates what?
When a substance is heated, a heating curve shows the changes in temperature as well as the physical state of the substance. A heating curve can chart the temperature versus the time elapsed as the changes take place.
A solid substance after heating coal or petrol?
coke
How do you change a substance change of matter?
By heating or freezing.
How do you change a substance state of matter?
By heating or freezing.
What are The differences between direct and indrect heating?
Direct heating involves transferring heat directly to the substance being heated, while indirect heating involves transferring heat to a medium, such as a fluid or gas, which then transfers the heat to the substance. Direct heating is more efficient and faster, while indirect heating provides better control over temperature and minimizes the risk of overheating the substance.
How heating a substance affect that substance?
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.
