When a flat sheet of copper is heated , the increase in its area is called cubical expansion.
The increase in the volume of a substance (solid, liquid, or gas) when heated, is called cubical expansion.
Across:
3. When a solid is heated, it in all the directions. 5. is an alloy of iron and nickel used in the making of pendulum. 6. A quantity which remains unchanged during thermal expansion of a solid is .
Down:
1. The increase in surface area of the solid on heating is called expansion. 2. There is increase in of metal rod during linear expansion. 4. glass is used for making kitchen glassware due to its low coefficient of cubical expansion.
