Adhesives are usually chemical compounds used to bind two materials together. Sealants are substances used to keep out other substances. Examples: Glue is an adhesive You put sealant on wood to keep it from absorbing water

Two examples of chemical changes are the rusting of iron and the combustion of gasoline. In chemical changes, new substances are formed due to the rearrangement of atoms.
1) a nail rusting 2) photosynthesis

A chemical change is a change that imply the change of the nature of molecules. Examples: neutralization of an acidic solution, thermal decomposition and generally all chemical reactions.
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
what are two example of chemical properties-^lyour dumb anyway two examples are oxidation and combustibility. and flammability and pH
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.
give me two examples of hardware
Physical and Chemical
Physical and chemical changes are harmful to us.
with which motion is N hook attached to straight strokes? Give two examples?
A physical change is when some thing's shape or volume is changed. But a chemical change is a reaction between two or more objects to create something new and you can't get back what you originally started with.
