Question

An Aluminum bar is 2 m long at a temperature of 20 degrees Celsius. What will it be at 100 degrees Celsius?

Answer 1

5

Explanation:

20*5=100

Answer 2

10 meters

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

`(2)/(20)=(x)/(100)`

Solve the equation for x

`x=(2*100)/(20)\\\\x=10`

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