Question

An iron ball falls from a height of 1 km of the ground. If all the energy is converted into heat, the rise in temperature of the ball will be (sp. heat of iron=0.1)a). 23.3 degree celcius.                      B). 2.33 degree celciusc). 233 degree celcius.                       D). 0.233 degree celcius

Answer 1

To calculate the heat energy you need multiply the mass(g) height(m) and the gravitational acceleration that is 9.8 m/s^2.

You get the heat in joules.
To find the rise in temperature,

Heat energy/mass x sp. of iron
