Answer:
35.14°C
Explanation:
The equation for linear thermal expansion is , which means that a bar of length
with a thermal expansion coefficient
under a temperature variation
will experiment a length variation
.
We have then = 0.481 foot,
= 1671 feet and
= 0.000013 per centigrade degree (this is just the linear thermal expansion of steel that you must find in a table), which means from the equation for linear thermal expansion that we have a
= 22.14°. As said before, these degrees are centigrades (Celsius or Kelvin, it does not matter since it is only a variation), and the foot units cancel on the equation, showing no further conversion was needed.
Since our temperature on a cool spring day was 13.0°C, our new temperature must be = 35.14°C
