Gases like ammonia and chlorine are readily soluble in water, whereas hydrogen is insoluble.The water level returns to its initial mark because the dissolved sugar particles break into smaller particles and get accommodated in the spaces between the water particles.When solid wax is heated, it melts into liquid wax and eventually vaporizes, and when cooled, the liquid wax freezes back into solid wax.Mass is the quantity of matter contained in an object and remains constant at all places, whereas weight is the force with which the earth attracts the object and changes from place to place.Water transitions into steam upon heating at 100°C, and transitions into ice upon cooling at 0°C.Solids are rigid and incompressible because their molecules are very closely packed with negligible intermolecular space and very strong intermolecular force of attraction.Liquids like vinegar, sugar syrup, and alcohol are miscible in water, while liquids like oil and diesel are immiscible in water.An oxygen molecule is made up of two atoms of oxygen.LPG comes out as a gas because opening the regulator valve releases the high pressure, allowing the liquid to expand back into its gaseous state.Gases are highly compressible and free to move in all directions because their molecules are far apart, with very large intermolecular spaces and negligible intermolecular forces of attraction.Atoms join together to form molecules, and molecules combine together to form matter.Gases can be liquefied and stored in a liquid state by applying high pressure, which brings their molecules closer together.The fragrance spreads quickly because the particles of gases are free to move in all directions and diffuse very fast.A nitrogen molecule is made up of two atoms of nitrogen.Solids like sugar and common salt are soluble in water, whereas solids like sand, mud, and wood are insoluble in water.When the intermolecular space is very small, the intermolecular force of attraction is stronger, and when the space is larger, the force is weaker.The interconversion of states of matter is the process by which matter changes from one state to another and back to its original state without any change in its chemical composition.A liquid has a definite volume but no definite shape, taking the shape of the container in which it is kept.Common examples of substances that undergo sublimation are camphor, naphthalene, and ammonium chloride.
