Examples of chemical changes in the nature?
Examples of chemical changes in nature include wood burning in a forest fire, photosynthesis, the formation of sulfuric acid in volcanic vents, and the fixing of nitrogen in lightning bolts and bacteria.
Similarities of chemical and physical changes?
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
What does physical and chemical change have in common?
A physical change to an object is a change in properties not involving the chemical makeup. In other words, a physical change is any change you can make to an object without changing the actual substance. (I.e. state of matter, size, shape, color . . .etc.) A chemical change is a change that forms a new substance through a chemical reaction. A chemical reaction is often signaled by bubbling or fizzing, but the only real way to prove a chemical reaction is by coming up with a new substance. So physical changes leave you with the same substance (slightly altered in appearance/texture etc.), but chemical reactions give you a new substance.
Are all physical changes accompanied by a chemical change?
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
What is the physical and chemical change that occurs when a birthday candle is lit on a cake?
There are multiple physical changes and chemical changes that occur when a candle burns. One physical change is that the candle melts back into liquid wax. One chemical change is flame burning on the wick.
Are all physical changes reversible with examples?
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.
What Are Changes That Occur In Nature?
Some common changes that occur in nature include the changing of seasons, the growth and decay of living organisms, shifts in weather patterns, and geological processes such as erosion and volcanic eruptions. These changes are part of the natural cycles that shape our environment.
Is boiling potatoes a chemical or physical change?
Physical, because it doesn't change chemical make up it just changes the appearance and texture
What are some common example of physical and chemical change that occur in the environment?
Some Physical Changes:> Water Cycle> Tearing of paper> Breaking of glassesSome Chemical Changes:> Photosynthesis ( the process of manufacturing food in plants )> ripening of fruits> burning> cooking
Examples of chemical changes in the nature?

What are some physical changes the occur during the teen years?
During teen years, pubic hair will grow, and there will be hair on the armpits also.
What are some physical changes when rusty metal is an example?
what are some physical changes when rusting metal is an example
What are some physical changes with steel?
Physical changes of steel can include changes in shape, size, or state, such as melting, freezing, or reshaping through hammering or bending. Steel can also undergo changes in color due to exposure to heat or oxidation. Additionally, steel can exhibit changes in strength and hardness through processes like heat treatment or cold working.
What are some physical change that occur at school?
If I had to guess, there are hundreds of different physical changes at school. Some good examples are when you sharpen your pencil, write on paper, or cut your lunch with a knife or fork. These examples are just a few ways that physical changes take place at school.
What would cause a ohysical change in a dog?
Physical changes in a dog may occur due to a variety of different reasons. Some possible causes include illness, the natural aging process or changes in weather.
Which of the physical changes release heat?
Exothermic reactions release heat as they occur, such as combustion, oxidation, and some neutralization reactions. Other physical changes that release heat include processes like freezing, condensation, and deposition.
What are some of the non physical changes which occur during adolescence?
There are many non-physical changes that occur during adolescence, most notably the large increase in the number of conections between neurons in the brain. this is what causes the sporadic behaviour in adolescents, and helps the brain and personality to develop by 'trimming' the unnecessary synapses. The flood of hormones (testosterone and oestrogen in men and women respectively) that causes the physical changes also cause a development in the sexuality of the adolescent (it makes the horny).
