4. Draw the heating curve for a substance if its melting point is 2℃ and boiling point is 90℃. Also, mention the states of matter exhibited by the various regions of the graph.
Answers
Given:
A substance has its melting point is 2℃ and boiling point is 90℃.
To find:
Draw the heating curve for a substance if its melting point is 2℃ and boiling point is 90℃. Also, mention the states of matter exhibited by the various regions of the graph.
Solution:
From given, we have,
A substance has its melting point is 2℃ and boiling point is 90℃.
The states of matter exhibited by the various regions of the graph are as follows:
Consider the attached figure while going through the following steps.
The substance will be in the solid-state first.
When the substance is heated, the substance starts to melt and then, the state changes to liquid-state.
By continuing the heating process, the substance starts to boil and then, the state changes to gas-state.
