Why can't all the mixtures be classified as solutions? a. not all mixtures are heterogeneous b. not all mixtures are homogeneous c. not all mixtures have solutes and solvents d. mixtures are made of only one substance.

C because A solution is a homogenous mixture at the molecular or ionic level of two or more pure substances that do not react with each other, whose components are in variable proportions.1 2 It can also be defined as a homogeneous mixture formed by a solvent and for one or several solutes.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
