Explanation:
The collision theory explains why reactions occur between atoms, ions, and molecules. With the increase in temperature, there is an increase in the number of collisions. Increasing the concentration of a reactant increases the frequency of collisions between reactants and will, therefore, increase the reaction rate.
The state of matter with a specific volume but no definite shape is the <u>Liquid</u> state.
<u>Explanation:</u>
There are three states of matter according to chemical science: Solid, Liquid and Gas. There is not much space in among the molecules. The particles in a liquid are free to float, so while a liquid has a certain volume it has no definite form. Liquids are composed of atoms or molecules bound by inter molecular bonds.
Most of the liquids resist compression while some do not, unlike a gas, a liquid will not spread to fill any container room and will retain a fairly constant density. A characteristic liquid state property is surface tension that results to wetting phenomena. Water is perhaps the most frequent substance on Earth.
