Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Can you give me a sentence for the word particular?
We shall discuss changes in properties selected for their particular interest.
Properties seen when one substance changes to another are known as?
there are two types of change. the first one is the physical change. the form or appearance of the substance is change but the chemical properties of the substance is not changed. example, water evaporates into the air, that is a physical change because from liquid, water changes into gas but it then comes back to water as rain. the other one is chemical change wherein the chemical properties of the substance is changed. example is burning of wood. wood is burned and turned into charcoal. the chemical properties of wood is different from the chemical properties of charcoal and charcoal is another substance.
The ability to dissolve in water and to conduct electricity are examples of what?
These are examples of physical properties.
What is 7 branches of chemistry?
Inorganic (no Carbon) Organic (Carbon) Physical (properties and changes) Biochemistry (life chemical reactions) Analytical (determines compostition) Theoretical (uses math and computers to predict properties and new compounds) Environmental (how chemicals affect the environment).
Which of the following are chemical properties changes temperature ripening evaporation humidity?
Just temperature.
Do chemical changes affect the chemical structure of a substance?
yes chemical properties do change a substance physical properties just change the physical shape or look!!!
What properties changes when substance changes?

What is an emample of a chemical change?
The following are indicators of chemical changes: ... For example, changing the color of a metal does not change its physical properties.
What are the products of physical change?
The products of a physical change are the same as what you started out with because their have been no changes to its chemical properties. Ex: If you rip a piece of paper, it's still paper.
What happens when you heat sulfur and copper together?

physical or chemical changes
