Answer:
answer is 17°C
Explanation:
The coefficient of thermal expansion is defined as
For linear expansion, it is just:
where
is the length and
is temperature.
is the change in length due to change in temperature at constant pressure.
For solids, we can neglect the pressure dependence, and also assume that if the temperature was increased linearly,
so change in temperature 10
then 27-10 is 17
