How are photosynthesis and respiration examples of chemical changes?
Both produce new molecules.
Are phase changes physical or chemical in nature?
A phase change is a physical change. It is not a chemical change.
In examples of chemical changes the odor of sour milk indicates a chemical change has taken place true or false?
True
What are the examlpes of chemical change and physical change?
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
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.
Are the changes produced by electrolysis chemical or physical in nature?
The changes produced by electrolysis are chemical.
What is the difference between physical and chemical change?
In a physical change the nature of the substance has not changed, just the way it looks, feels or tastes. Examples of physical changes are: glass breaking, water changing into ice, whipping cream. In chemical change the nature or chemical composition of the substance is changed. Examples of chemical change are: iron changing to rust, burning leaves, food spoiling.
Is a inflation of a car tire a chemical change?
No. Nothing changes in its chemical nature.
Does chemical changes almost never occur in nature?
no
Which one is not an example of a chemical change Leaves on trees changing color A cake baking Food being digested All are examples of chemical changes?
All are examples of chemical changes
What is a non example of chemical changes?
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
What are examples of a chemical change in matter?
Synthesis, decomposition, combustion, and oxidation are some examples of chemical changes (reactions) of matter.
What are examples of chemical changes that happen in your environment?
volcanic eruption
Is ductility a physical or a chemical change?
Being ductile, malleable, freezing, melting are some examples of physical changes of a substance. Physical changes do not form a new substance while chemical changes do. Examples of chemical changes are a rusting nail and combustion.
What are some examples of a chemical change in matter?
Examples of chemical changes of matter include, but are not limited to: color change, formation of a precipitate, formation of a gas, change in energy.
Examples of a physical change or a chemical change?
Physical changes can range from colour changes to change in tempricture.
What are the type of changes in baking a cake?
The most important changes are of chemical nature; water evaporation is a physical process.
