How does the change produce by heating a wood splinter differ from that produced by heating a glass tubing?
Heating a wood splinter will lead to combustion, resulting in the release of smoke, ash, and gases due to the breakdown of the organic material. On the other hand, heating glass tubing will not combust; instead, it undergoes physical changes, such as expansion or contraction, depending on the temperature change. Glass may also soften or melt depending on the temperature, but it will not produce combustion byproducts like wood.

Is heating a wood splinter a chemical change and why?
Heating the wood (and not burning it) would be a physical change. If the wood splinter catches fire and burns, then it is a chemical change because a combustion reaction has taken place and the wood is no longer the same chemical composition. It will turn into carbon dioxide and water, and other materials left over.
Is heating and cooling are examples of a chemical change?
Heating can be due to a chemical change, for example burning a fuel is in effect a chemical reaction with oxygen. Also some chemical reactions are exothermic, ie they produce heat. Not so many produce cooling, but one is the combination of ice and salt.However heating and cooling happen for other reasons as well, so you can't say they are examples of chemical changes. It is correct to say that some chemical changes result in heating and cooling.
Why Iron expands on heating is a physical change?
Iron expands on heating due to an increase in the kinetic energy of its atoms, causing them to vibrate more and occupy a larger volume. This process does not alter the chemical composition of iron; it remains iron throughout the expansion. Since the change is reversible and does not produce a new substance, it is classified as a physical change.
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.

Is heating KClO3 and MnO2 a chemical or physical change?
Heating KClO3 and MnO2 to form KCl and MnO2 is a chemical change as new substances are being produced.

How does a guitar string's physical change produce sound?
The sound is produced by the vibration of the string.
When a green powder is heated it turns black and a gas is produced is this a reversible or irreversible change?
when green powder is heated, it turns black and a gas is produced. in irreversible changes, new materials are always formed. given that a gas is produced, which is a new material, heating green powder is an irreversible change.

Heating is a physical change.
Can a marble rock change to a basaltic rock if washed into the ocean?
No, marble is made by heating and squashing limestone while basalt is produced out of volcanoes. One can not change into the other by immersing it in sea water.
How does energy and nutrients change throughout your lifetime?
Well, harmones that are produced when we sleep change as we grow older and it makes us produce more grease on our body.
