Question
Solids and liquids expand on
Solids and liquids expand on
Open in App
Solution
The correct options are
A heating
D cooling
On heating, solids and liquids expands in terms of size and volume. This is because on heating, their molecules or particles gain energy and become more active. Hence they start to move around quickly thereby increasing the size. On cooling, the reverse phenomenon happens. The active molecules or particles of the matter become passive thereby decreasing the size.
