Ill give you more than 2.putting water in to the refrigerator to freeze it
cutting wood
dropping plates, or cups
chopping fruits or vegetables
tearing paper
breaking items
chewing pencils
peeling potatoes
Melting ice into water and breaking a glass bottle are examples of physical changes. These changes do not alter the chemical composition of the substances involved, only their physical state or appearance.
Yes. For example, water changing to steam (evaporation) is a physical change. While the water is now a gas (steam) & no longer a liquid, its chemical composition is still the same: H2O (2 atoms of hydrogen & 1 atom of oxygen)
Because there are currently four known states of matter, one change between each of these states yields three different types of state change. One is the change from a solid to a liquid, which we will call "melting." The second is the change from a liquid to a gas, which we call "vaporization." The third is the change from a gas to a plasma. There are terms for these changes in the reverse direction, and sublimation describes the change from a solid to a gas with no intermediate liquid phase.
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.

1. breaking a rock in half 2. ripping a piece of paper
The physical properties refer to the change in it's physical state like "shape", " size" etc. physical changes involve only the change of physical state. No heat or light is involved. Normally we can get the original form of state after the process for example :- 1) change in shape of balloon changes when we blow air into it 2) the paper can be crush and then the shape can be regained. 3) when the wax melts it's shape can be regained by solidification
Melting ice into water, cutting a piece of paper into smaller pieces, and mixing sugar in water are all examples of physical changes because they alter the form or structure of the substances without changing their chemical composition.
Like and as 1. as red as a rose. 2. bright like the sun.
Ice melting, water boiling and cutting paper. It usually has to do with changing the shape or state of the matter.
Yes. For example, water changing to steam (evaporation) is a physical change. While the water is now a gas (steam) & no longer a liquid, its chemical composition is still the same: H2O (2 atoms of hydrogen & 1 atom of oxygen)
Dogs and oak trees are examples of multicellular organisms.

1. First step: a physical change 2. Second step: a chemical change
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.

yes they are one of the 7 physical properties===========================Would they not be 2 of the 7 ?
