Answer: V= 4.2L
Explanation: To solve for the new volume we use Boyle's Law.
P1V1 = P2V2
Derive for V2 the new volume.
V2 = P1V1 / P2
V2 = 1.8 atm x 2.8 L / 1.2 atm
= 4.2 L
Answer:
Giant structures are usually arranged in to giant regular lattices and they are extremely strong because they have many bonds involved. Simple molecules are just normal molecules as the name suggests like CO². though it contains strong covalent bond it still has weak intermolecular forces

Answer:
There's good reason why vitamin D is called “the sunshine vitamin.” When your skin is exposed to sunlight, it makes vitamin D from cholesterol. The sun's ultraviolet B (UVB) rays hit cholesterol in the skin cells, providing the energy for vitamin D synthesis to occur.
Explanation:
When a cold air mass meets a warm air mass, a front is formed; if the cold air is replacing the warm air, it is known as a cold front. Cold fronts frequently cause rain showers or thunderstorms because they force air in a steep upward direction at the front's edge. They also bring about changes in wind direction and atmospheric pressure.
