Explanation:
Melting point help us to determine if a mixture is pure or has impurities by the virtues of it melting range..
Pressure can affect the boiling pressure of a substance
as when pressure increases the particles are closer together and so require more energy to boil therefore increasing the substances boiling point
hope that helps
Answer:
Option =C each mouse in the study has brown ears.
Explanation:
Qualitative:
Qualitative properties are those that can be only observed but not measured in numerical values. These are observed through senses: touch, sight, smell, taste and hear.
For example:
Color, odor, brittleness, taste etc.
Quantitative:
Quantitative properties can be measured in numerical values.
For example:
Melting point, boiling point, conductivity, viscosity, density, hardness and solubility.
In short we can say that qualitative is a measure of quality while the quantitative is a measure of quantity.
