Colligative properties are those properties of a solution that depend only on the concentration of solute molecules or solute ions present in the solution but not on the identity of the solute.
The following are examples of colligative properties; vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.
Colligative properties depend on the nature of the solvent and on the solution concentration but not on the identity of the solute.
. A closed system allows only energy transfer but no transfer of mass. Example: a cup of coffee with a lid on it, or a simple water bottle. ... In reality, a perfectly isolated system does not exist, for instance hot water in a thermos flask cannot remain hot forever.
The amount of gravity is directly proportional to the amount of mass of the objects and inversely proportional to the square of the distance between the objects. Gravity is a force that increases the velocity of falling objects - they accelerate.
