In a Physics experiment, a bar of aluminum, initially 80 cm (0.80 m) long, is brought from room temperature of 23^oC to 100^oC by surrounding it with steam. By how much does the aluminum bar expand?
From a table we find that the coefficient for linear expansion for aluminum is

= 24 x 10 ^{- 6} (C^o) ^{- 1}
