The layer of Earth’s atmosphere that has the coldest temperature range is mesosphere
Answer:
D. Quantitative
Explanation:
Quantitative observation deals with numbers, or amounts.
Qualitative observation deals with de- scriptions that cannot be expressed in numbers.
Density is a property of the substances that is obtained by dividing its mass by the volume. For a rectangular solid, the volume may be solved by the following equation,
V = L x W x H
Substituting the given values for the dimension,
V = (2.30 cm) x (4.01 cm) x (1.82 cm) = 16.78786 cm³
Calculating for the density,
Density = mass / volume
Density = 25.71 cm / <span>16.78786 cm³ = 1.53 grams per cm</span>³
Thus, the density of the given solid is approximately 1.53 grams per cm³.
<span>If a solution conducts electricity, it it positive evidence that solute dissolved in solvent is electrolyte.</span>
the answer is A......
it is supported by practical evidence and examples. this is the answer because he tried and tested many different ways to see what would happen so he is happy with the conclusion that what he tested is what he gets.
