How much energy does it take to melt 1g of ice? Using the equation for a change in temperature and the value for water from table 1 we find that q = ml f = (1.0 kg)(334 kj/kg) = 334 kj is the energy to melt a kilogram of ice.

How much heat is needed to melt 55.49 g of ice. This is a lot of energy as it represents the same amount of energy needed to raise the temperature of 1 kg of liquid water from 0ºc to 79.8ºc. How many joules does it take to melt 1. Calculate the heat to warm the ice, then the heat to melt the ice, and finally the heat to warm the liquid water.
The sum is the total heat required. For water, it takes some 4.185 joules to raise water 1 gram 1 degree, which for 225 grams and 101 degrees (from 0 to 100) would be 225 * 101 * 4.185 j then you have to add in 225 * raising ice temperature (2.09 joules per gram. The molar heat of fusion of ice is 6.01 kj/mol.
The sum is the total heat required. How do you find the minimum heat needed to melt ice? Current prediction for the next sunspot cycle maximum gives a smoothed sunspot number maximum of about 58 in july of 2013.
We are currently two years into cycle 24 and the predicted size continues to fall.
