Answer 11

Tell us the temperature at which the substance will boil or melt. This helps us to classify substances as solids, liquids or gases at a specific temperature.

Question 12

Define mixtures?

Answer 12

A mixture is a combination of two or more substances, where these substances are not bonded (or joined) to each other and no chemical reaction occurs between the substances.

Question 13

In a mixture, the substances that make up the mixture are?

Answer 13

not in a fixed ratio

keep their physical properties

can be separated by mechanical means

Question 14

What is a Heterogeneous mixtures?

Answer 14
