Question

An iron sheet is 5m long and 2in broad. It is heated through 60°C Calculate the change in surface area of the sheet Coefficient of superficial expansion of iron is 2.4 x 10^-5/°C​

Answer 1

Answer:

sorry if worng

Explanation:

1.  

Heat is a form of energy that follows from a body of higher temperature to one of lower temperature.

Temperature is a degree of hotness or coldness of a body.

Answer 2

Answer:

Here original area, A = 5 × 2m² = 10m², increase in temperature, ∆T = 60°C and coefficient of superficial expansion B sign = 2.4 × 10–⁵/°C.
