Calculate the amount of heat energy to be supplied to convert 2 kg of ice at 0 °C completely into water at 0 °C if latent heat of fusion for ice is 80 cal/g.
1. Latent heat of fusion:
The quantity of heat required to convert unit mass of a substance from its solid state to the liquid state, at its melting point, without any...
1. The energy required to completely separate the molecules or atoms in liquids is greater than the energy needed to break the rigidity (rigid bonds between the molecules or atoms)...
(A) 136 km
When the piece of ice falls from the height h, it possesses potential energy, mgh.
This P.E. is converted to heat energy.
∴ Q = mgh
But only \(\frac{1^{th}}{4}\) of it is absorbed...
