How many Joules of energy are required to make 50 kg of ice completely melt? Hv = 226,000 J/kg
Hf = 334,000 J/kg

In order to answer this question, you need the enthalpy of fusion of ice, which is 333.55 J/g (Joules/gram). The enthalpy of fusion is the amount of heat that must be absorbed or lost in order to change physical state.

The number of Joules required to melt the ice = enthalpy of fusion of ice x mass of ice.

1 kg = 1000g

40kg x (1000g/1kg) = 40,000g

Joules needed to melt the ice = 333.55 J/g x 40000 g = 13342000 J or

1.3342 x 107 J

Explanation:

Instead of 40kg input 50kg and get the answer

The law of falling bodies is one of Galileo's key contributions to physics. It states that objects fall at the same speed regardless of weight or shape. Through his experiments, Galileo countered the pervasive Aristotelian view, which held that heavier objects fall faster than lighter objects.
