Question

A 250g copper pipe is heated from 283k to 304k what is the energy needed to heat the pipe?the specific heat capacity of copper is 390J/kg-1 degree Celsius-1

Answer 1

We can find the energy needed to heat the copper pipe from the formula:

$$Q=mc\Delta T,$$ $$Q=0.25\ kg\cdot 390\ \dfrac{J}{kg\cdot K}\cdot(304\ K-283\ K)=2047.5\ J.$$

Answer:

$Q=2047.5\ J.$
