Question

What is the co-efficient of linear expansion of a rod if it is found to be 100 m long at 20°C and 100.14 m long at 100°C?​

Answer 1

Answer:

1.75 mm / celsius

Step-by-step explanation:

To find the co-efficient of linear expansion, we must use the formula:

$\frac{length 2 - length 1}{temp 2 - temp 2} = \frac{100.14-100}{100 - 20} = \frac{0.14}{80} = 0.00175 m/celsius =1.75 mm/celsius$

Answer 2

Answer:

1.75 mm Celsius
