A piece of aluminum house siding is 3.40 m long on a cold winter day of -28°C. How much longer is it on a very hot day at 37°C?

Answer:

49 millimeters

Step-by-step explanation:

To determine how much longer the aluminum house siding is on a hot day at 37°C compared to a cold day at -28°C, we can use the coefficient of linear expansion for aluminum.

The coefficient of linear expansion for aluminum is approximately 22.2 x 10^(-6) per degree Celsius. This means that for every 1°C increase in temperature, aluminum expands by 22.2 x 10^(-6) times its original length.

First, we need to calculate the temperature difference between the hot day and the cold day:

Temperature difference = Hot temperature - Cold temperature

Temperature difference = 37°C - (-28°C)

Temperature difference = 37°C + 28°C

Temperature difference = 65°C

Next, we can calculate the increase in length using the coefficient of linear expansion:

Increase in length = Coefficient of linear expansion * Original length * Temperature difference

Increase in length = 22.2 x 10^(-6) * 3.40 m * 65°C

Increase in length ≈ 0.049 m

Therefore, the aluminum house siding would be approximately 0.049 meters (or 49 millimeters) longer on a very hot day at 37°C compared to a cold day at -28°C.
