Everyday Examples of Convection
boiling water - When water boils, the heat passes from the burner into the pot, heating the water at the bottom. This hot water rises and cooler water moves down to replace it, causing a circular motion.
Explanation:
1 L ------------------ 1000 cm³
1.30 L --------------- ??
1.30 x 1000 / 1 => 1300 cm³

How to differentiate between physical and chemical change?
Physical and Chemical Changes to Matter
Physical changes only change the appearance of a substance, not its chemical composition.
Chemical changes cause a substance to change into an entire substance with a new chemical formula.
Chemical changes are also known as chemical reactions.
Answer:
Explanation:
<u>1. Chemical equilibrium equation:</u>
<u>2. Species</u>
In an equilibrium constant expression you do not include the solid substances; only gases and dissolved substances.
The symbol means solid, thus Cu(s) and Ag(s) shall not appear in your equilibrium constant expression.
The symbol means in aqueous solution, thus the both and must appear in the equilibrium constant expression.
<u>3. Equilibrium constant expression.</u>
It is the quotient of the product of the concentrations of the species on the right hand side of the equilibrium equation, each raised to its corresponding coefficient, and the product of the concentrations of the species on the left hand side, each raised to its coresponding coefficient.
