Answer: Option (b) is the correct answer.
Explanation:
In solids, atoms are held together because of strong intermolecular forces of attraction between them.
As a result, solids have a definite shape and volume. Hence, its molecules are not able to slide past each other.
Whereas in liquids, molecules are together by less strong forces as compared to solids. Therefore, liquids do not have fixed shape and volume. They occupy the shape of a container in which they are kept together.
Therefore, molecules of a liquid are able to slide past each other.
In gases, molecules are held by weak Vander waal forces. So, they collide rapidly and occupy the volume of container and not the shape. Similarly, plasma is a hot ionized gas which consists of positive ions and negative electrons. Like gases, plasma also occupies the volume of a container.
Thus, we can conclude that liquid is the matter which can fill a container from top to bottom.

Answer:
n a chemical reaction, delta H represents the sum of the heats of formation, commonly measured in kilojoules per mol (kJ/mol), of the products minus the sum of those of the reactants. The letter H in this form is equal to a thermodynamic quantity called enthalpy, representing the total heat content of a system.
