Answer:
The correct answer is , Weak bonds are transient and easily reversible.
Explanation:
Molecules or atom that associate to produce a weak bond can interact, and then separate .this is evident in hydrogen bond and vanderwaal force where the combined effect can produce emergent properties.
Example; the hydrogen bonds present in water molecule; when the bonds are broken using heat, the molecules are separated or released in form of vapor, this same molecule can combine again by condensation to produce liquid. showing clearly how transient and reversible the bonds between them is.
Explanation:
a material system in which mass or energy can be lost to or gained from the environment.
The transport of O2 from the outside air to tissue cells and the transport of CO2 from tissue cells to the outside is known as.... gas exchange.
Explanation:
A gas is state of matter in which there is large intermolecular distance and hence, a weaker molecular force of attraction in comparison to solids and liquids. therefore, it impart certain properties to gases which are uncommon in solids and liquids
Properties of a gas includes:
Exert pressure on the container
Highly compressible
Low density
and readily soluble in other mediums
Hence, high density is not a property of a gas.
