Answer:
True
Explanation:
the relative amount of a given substance contained within a solution or in a particular volume of space; the amount of solute per unit volume of solution;.
The correct answer for the question that is presented is this one: "become extinct." If the bird species cannot adapt to eat a different source of food, this species of bird will most likely become extinct. Given the fact that t<span>he climate of the location changes very quickly, and the ecosystem becomes too cold for fruit trees to survive.</span>
Answer:increase In kinetic energy of molecules
Explanation:increase in kinetic energy of molecules
Correct Answer: Option g: <span>adding salt to water lowers its freezing point
Reason:
Freezing point is a colligative property. When a non-volatile solution is present in solution, it's freezing point decreases. This is referred as depression in freezing point (</span>ΔTf<span>). Extent of lowering in freezing point is dependent on number of particles present in system. Mathematically it is expressed as:
</span>ΔTf = Kf X m
<span>
where, m = molality of solution
Kf = cryoscopic constant.
Hence, a</span><span>dding salt to water lowers the freezing point of solution.</span>
