Can matter undergo changes in both its physical and its chemical properties Explain please?
No.
Can electricity and light bring reversible or irreversible change explain your answer?
Reversible: the light goes on, producing illumination; it goes off and it's as dark as it was. Irreversible: light causes a plant to grow which is not immediately reversed when the light is turned off
Is rusting of iron an irreversible or reversible change also explain?
There isn't really any such thing as an irreversible change, just changes that are so difficult they are unlikely to happen. It's a chemical change, because rust is a different substance from iron. If you put rust into a very hot furnace with carbon you can reduce it back to iron.
How do you explain why phase changes are reversible?
explain why phase changes are reversible for solid to liquid and gas to liquid
Explain how breathing on glassis an example of a reversible change?
Breathing on glass is an example of the reversible change because, the air inside the glass can be breathed in again.
Is the first law of thermodynamics applicable to irreversible process also.. Explain?
yes since it is law of energy balance so irrespective of the process it can be applied to any process but small change comes when we deal with reversible and irreversible processes. it can be explained in text form : please give attention to the text; CHANGE IN TOTAL ENERGY( it is sum of change in macroscopic kinetic energy and change in macroscopic potential energy and change in internal energy,U) = HEAT TAKEN BY THE SYSTEM {actually heat taken by the medium which we use often an ideal gas}(sum of heat given to the system from outside+ heat generated with in the system ) + WORK DONE BY THE MEDIUM OR SYSTEM {again it includes all kind of works such as expansion work shaft work electrical work etc. also when the process is IRREVERSIBLE it includes internal work which is consumed to overcome the friction} for reversible processes there is no dissipation of internal heat and internal work in that case we consider that the piston cylinder which we use to explain first law is frictionless . and also since they have a characteristic property of INFINITE SLOWNESS the reversible process can be considered at equilibrium at each state. For irreversible processes the heat is generally generates with in the system because we do not use the friction less piston cylinder arrangement.
What happens in reversible reaction?
Reversible: When reactions are reversible, it means that, it can go both forward and backward. E.g: *A and B react to C and D but in reversible reactions C and D react to or from A and B. *Water can be ice and ice can be water.

A chemical change is indicated if a new material is formed Yet dissolving salt in water makes salt water but it is considered to be a physical change Did someone mess up Explain?
During dissolution salt is not transfotmed in another compound; also dissolution is reversible.
