Q1: Gases diffuse easily through amorphous or porous solids.
Q2:All changes in phase are called change in state of matter.
Answer:
Explanation:
Gases diffuse easily through amorphous or porous solids. Usually solids are densely packed with no space. But porous solids can help in diffuse gas into them. Due to the vacancy present in these solids, gas can easily diffuse through these types of solids.
Similarly, the phase changes lead to change in the state of matter. As the basic of change in phase leads to change in its state from solid to liquid or from liquid to gas or vice versa. So change in state of matter will occur in any change in phase.

Explanation:
Explanation:
The dipoles in CO are in opposite directions so they cancel each other out, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces. Water (H2O) has hydrogen bond present which is a polar bond which has a high intermolecular force.
Water which has high intermolecular force will require more energy that is a higher temperature to overcome these attractions and are pulled together tightly to form a solid at higher temperatures, so their freezing point is higher.
As the temperature of a liquid decreases, the average kinetic energy of the molecules decreases and they move more slowly.
CO with lower intermolecular forces will not solidify until the temperature is lowered further.
