1. What is the difference between a chemical and physical change?

2. What is the difference between a property and change?

Respuesta :

Physical change changes it’s physical look but doesn’t change what it is or it’s composition. Chemical change changes the composition.

Physical properties are those that can be observed without changing the identity of the substance. Chemical properties are those that can be observed only when a substance is changed into a new substance. ... Chemical changes are changes that occur when one substance is turned into another substance.

Answer:

1. What is the difference between a chemical and physical change?

physical change :-

  1. no substance is formed
  2. properties of components before and after are the same
  3. reversible
  4. example:- solubility, melting, condensation and boiling

chemical change :-

  1. new substance is formed
  2. properties of components before and after are different
  3. irreversible
  4. example:- burning, rusting, oxidation and neutralisation

2. What is the difference between a property and change

change:-

A physical change in a substance doesn't actually change what the substance is. It remains the same. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.

property:-

A physical property is an aspect that can be observed or measured without being changed. A chemical property may only be observed by changing the chemical identity or substance.
