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
Solve the equation for x
Thus, at 100 degree Celsius, the aluminium bar is 10 meters long.
