What is the difference between physical and chemical change give examples?
CHEMICAL CHANGE: Such change is a permanent change and substances go through such changes not only alter their outer shape but also change their composition. For example: conversion of milk into yoghurt is a chemical change PHYSICAL CHANGE: Such change is a temporary change and substances go through such changes alter their shape and volume only but composition remains same. For example: water changes into ice and ice melt to water is a physical change.
Is formation of water when hydrogen burns a chemical change or a chemical property?
It's a chemical change. Any time you have a change in the chemical formula of a substance, you have a chemical change. The chemical formula of hydrogen is H[2], and the chemical formula of oxygen is O[2]. The chemical formula of water is H[2]O. 2 H[2] + O[2] --> 2 H[2]O. If you were watching this happen in a lab, you'd watch two colorless gases react to form a single colorless liquid. A change in state (solid, liquid, or gas) that cannot be due to heating or cooling is nearly always a sign of a chemical change.
How do we know a chemical change has happened?
You can tell if something is a chemical changes or a physical change. Examples: Question 1) Ice melting. Answer 1) Physical change because nothing has changed just the shape of the ice. Reversing ice is easy. Question 2) Wick on a candle changes colour from white to black. Answer 2) Chemical change because it changes from clack to white and will be hard to reverse. So if it is a chemical change taking place it hard to convert back or reverse. You can also tell by the change of colour.
