The two types of physical properties are intensive and extensive. Intensive properties do not depend on the amount of a substance. An example of an intensive property is density. Extensive properties do depend on the amount of a substance. An example of an extensive property is mass.
Melting: change of phase from solid to liquid
Boiling: change of phase from liquid to a gas
freezing and melting are physical changes
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
Well a Chemical change means that what ever changes can't change back. For example if u have normal paper then burn it that's a chemical change and that's why a chemical change is so important.
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.
water into ice water into steam both above are the physical changes physical changes means reversable change which can be brought into its original state eg:steam can be converted into water by cooling and ice into water upopn heating............ its true try it............
These are physical and chemical changes.

freezing and melting are physical changes
enzymes, pancreation, amylase, changes starch into the disaccharidemaltose a sugar makes 2 glucose molecules
Intensive/Intrinsic and Extensive/Extrinsic:)2 types of physical changes are...1) If you freeze water it turns into ice- it is reversible because you can melt the ice and it turns back into water.2)REMEMBER: not all Chemical reactions are irreversible!!!!!!!!!!!!
1.Having menstruation 2.Enlargement of breast 3.Enlargement of hips
it causes the 1. melting of solid substances 2. the solidification of liquid substances\ 3. the deformation of matter.

There are four different types of organization changes. The changes are: strategic, structural, process- oriented and people- centered.
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
1. breaking a rock in half 2. ripping a piece of paper
1. Bending 2. Painting 3. Breaking 4. Scratching 5. Cutting
