The linear expansivity of brass is 2 × 10^-5 °C^-1 if the volume of a piece of brass is 10cm3 at 0°C, what will be its volume at 100°C?
Now for the right answer to the above question:
- A is the right answer.
- B is incorrect.
- C is incorrect.
- D is incorrect.
You may please note this/these:
- Volume expansivity = 3 × linear expansivity
- Volume expansivity = (change in volume) / (original volume × change in temperature)
