Answer:
a. Expansion: the spatial dilation of a material that occurs upon changes in its composition. (an increase in number or amount to become larger in size.)
E.g- in a thermometer, when it gets hotter, the liquid inside them expands and rises up the tube.
b. Sublimation: the process in which a solid changes directly into a liquid.
E.g- dry ice, solid iodine and ammonium salts.
when the above solids are heated, only particles which are found on the surface of the solid have enough energy to break all forces of attraction and form a gas.
c. Contraction: it is the opposite of expansion. when a liquid is cooled the particles slow down and contract.
E.g- when a thermometer is taken out of your mouth, it contracts and the liquid inside falls back to the bottom.
f. Random Motion: motion in which the particle moves in a zig-zag manner and not in a straight line. The kinetic particle theory states that matter is made up of particles which are in constant <em>random motion,</em>
Explanation:
C - rising and cooling, causing water vapor to condense
I think it would have 10 neutrons. Hope this helps :)
Answer:
All of the above.
Explanation:
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances.
This process is not reversible and a change of energy that is sometimes heat is given off.
