Match each item with the correct statement below.
Semenov [28]
The terms and their definitions are as follows:

1. Energy
B. The capacity to do work.
Energy comes in different forms, each relating to a different type of work. For example, kinetic energy and potential energy.

2. Volatile
D. Substance that changes to gas easily at room temperature
Volatile substances do not have strong attractive forces between their molecules, so they are easily overcome at room temperature and the substance evaporate. For example, petrol.

3. Chemical Reaction
H. Another term for chemical change

4. Chemical Change
G. <span>The change of one or more substances into other substances
</span>Chemical changes involve rearrangement or removal of atoms from a substance

5. Endothermic
J. Any chemical reaction that absorbs energy
These reactions require the addition of heat energy to take place

6. Exothermic
F. Any chemical reaction that gives off energy
Exothermic reactions are associated with a rise in temperature of the system

7. Density
I. The amount of matter contained in a unit volume
Density is characteristic of a substance and independent of the amount that is present

8. Physical property
A. Can be observed without any change in the identity of the substance
Physical changes include breaking and state changes

9. Law of conservation of mass
E<span>.The fact that matter can be neither created nor destroyed in a chemical change. 
This is true for any reaction in the universe

10. Chemical property
</span><span>C. Can be observed only when there is a change in composition of a substance

Which substance has the highest particle mobility?
lapo4ka [179]

steam at 105 °C because gas particles are the most mobile and mobility increases with increasing temperature

Explanation:

The substance with the highest mobility would be steam at 105 °C because gas particles are the most mobile and mobility increases with increasing temperature.

Mobility is the movement of the particles in a medium.

It increases the randomness of particles.

  • Of all the states of matter, gases are the most random of all.
  • Also, mobility increases with increase in kinetic energy.
  • As temperature increases, kinetic energy will also increase and cause more mobility.
