| Cubical Expansion |
|
| Increase in volume of a solid on heating is cubical expansion. |
| |
| Let V1 = Initial volume at t10C |
| |
| V2 = its volume at t20C (t2>t1) |
| |
Then increase in volume ' v' = v2-v1 |
| |
Increase in temperature ' t' = t2-t1 |
| |
| The coefficient of cubical expansion is defined as the ratio of the increase in volume to its original volume for every degree
increase in temperature. It is denoted by 'g'. |

| We can show that g
