Calculate the heat energy required to melt 4kg of ice when the specific latent heat of fusion of water is 334,000 J/kg. 1336 kJ

2336 kJ

3336 kJ

HELP ASAP

We have given in the question that,

We know that,

Amount of heat required = Mass * specific heat * change in temperature

[ Specific Latent heat of fusion is the amount of heat required to change one mole of substance from solid to liquid phase without changing in temperature .]

But, For complete melting of substance without change in temperature

Amount of heat required = Mass * Specific latent heat of fusion

Subsitute the required values,

Where,

Now,

Hence, The amount of heat required to melt 4kg ice is 1336KJ

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
