Calculate the energy transfered when 3 of copper is heated from 20°C to 220°C

Q = 231.6 J

Explanation:

Given that,

Mass, m = 3 g

The temperature rises from 20°C to 220°C.

We know that, the specific heat of copper is, c = 0.386 J/g K

We know that the energy transferred in heating of copper is given by :

So, the required energy is equal to 231.6 J.

c)as speed changes, wavelength and frequency change.

everything changes!

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
