Enthalpy changes accompanying a change of state are than those accompanying the heating of a substance at each state?
Any change of state involve a change of the system enthalpy.
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.

What do the terms 'boiling' and 'simmering' mean?
Boiling is heating any liquid substance over its boiling point, till it changes its state.. Simmering is continuously heating any liquid substance to keep it hot..
What changes occurs in heating sugar?
When sugar melts it turns into a brown sticky substance we know as caramel.
What Enthalpy change?
The enthalpy change equals the energy transferred from the environment through heating or work other than expansion work.
Are the atoms in a substance the same if the substance changes states?
On heating there will be a change in the physical state not chemical composition. So the number of atoms will be the same even after change in state.
How do energy and changes in energy change the state of matter?
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.
What is a solid substance left after heating coal or petrol?
i am a solid substance left after heating coal or petol
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.
How is the kinetic energy of the particles that make up a substance different after it changes?
If you mean by heating it... When you heat a substance, the thermal energy of its particles increases. This means that the particles will move around faster as they have a higher kinetic energy.
what is the answerA heating curve shows how the _____________ (y-axis) changes as a substance is heated up at a constant rate over _____________ (x-axis).?
