Answer:

10 meters

Step-by-step explanation:

Let at 100 degrees Celsius, the aluminum bar is x m long.

We have been given that aluminum bar is 2 m long at a temperature of 20 degrees Celsius.

Thus, we have the equation

\frac{2}{20}=\frac{x}{100}

Solve the equation for x

x=\frac{2\times100}{20}\\\\x=10

Thus, at 100 degree Celsius, the aluminium bar is 10 meters long.
