Answer:

a. High vapor pressures

b. Weak intermolecular forces

Explanation:

a. Sublimation occurs when the vapor pressures is equal to the applied pressure in the solid. Therefore, the higher the vapor pressure, the easier it is to be equal to the external pressure and the most likely is the solid to sublime.

b. Sublimation requires intermolecular forces to be weakened in order to go from the solid state to the gas state. Therefore, the weaker the intermolecular forces, the easier sublimation will be.

g The boiling of water is a Question 4 options: chemical and physical damage chemical change because a gas (steam) is given off
Strike441 [17]

Answer:

physical change because the gaseous water is chemically the same as the liquid

Explanation:

Matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states.

Generally, matter exists in three (3) distinct or classical phases and these are; solid, liquid and gas.

A physical change can be defined as a type of change that only affects the physical form of a chemical substance (matter) without having any effect on its chemical properties. Thus, a physical change would only affect the physical appearance and properties of a chemical substance (matter) but not its chemical properties.

This ultimately implies that, a physical change result in a change of matter from one form or phase (liquid, solid or gas) to another without a corresponding change in chemical composition.

Hence, the boiling of water is considered to be a physical change because the gaseous water is chemically the same as the liquid i.e there isn't any changes in chemical composition of water when boiling.
