Question

Q.4 Which one will boil at a constant temperature? *
O True solution
O Compound
O Colloid
O All the above​

Answer 1

Answer:

compound

Explanation:

compound has the constant boiling point

Answer 2

Compound boils at a constant temperature because it has a definite composition.

Why compound has a constant boiling point?

• Compounds are pure substances. They are made up of chemical elements in a fixed proportion.
• A pure substance's particles are all the same. They share a similar composition and features. Pure substances, such as compounds, have stable boiling points for this reason.

Why True solutions and Colloids don't boil at constant temperatures?

• True solutions and Colloids are mixtures.
• They are made up of two or more things that have been mixed. The melting and boiling points of all the substances are different. This is the primary reason why mixtures lack a stable melting or boiling point.

Therefore, the compound being a pure substance boils at a constant temperature while mixtures like true solutions and colloids don't boil at a constant temperature.
