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.
Joules needed to melt the ice = 333.55 J/g x 40 g = 13342 J

How many joules are required to melt 12.8 g of ice at 0 and degC?
To answer this, you need to know the ∆Hfusion of water, which happens to be 334 J/g. So, to melt 12.8 g of ice at 0ºC, the joules needed = (12.8 g)(334 J/g) = 4275 joules
What must occur for a solid to melt?
Heat... Quite simpleTry it yourself, nothing cant melt without heat
What materials change by heat?
Many materials such as plastic melt and some materials burn such as wood
Is it hard to melt gold?
no its easy...first we should give it a heat and then melt it
What is wax susceptible?
It is susceptible to heat -- it will melt.
How many kilocalories are required to melt 16g of ice?
This heat is 32,48 joules.
How many joules of heat are necessary to melt 500g of ice at its freezing point?
334 j/g =167000 j

How many joules of heat are necessary to melt 500g of ice ar its freezing point?
334 j/g =167000 j
How many joules of heat are necessary to melt 500 g of ice at it's freezing point?
Heat required to melt 1 g of ice at 0°C is approximately 80 cal . This is also called latent heat of fusion of ice.
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
How many joules of heat are required to melt 40 kg of ice at 0 dg C?
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
How many joules are needed to melt 2 grams of water?
2,26 Kj are necessary
How many joules of energy are needed to melt 54-grams of ice at its melting point?
The specific latent heat/ latent heat of fusion of ice is 333.55 J/gtherefore by using the equation E=mLE = 54 * 333.55= 18011.7 JTherefore the energy needed to melt 54 grams of ice at its melting point which is keeping it at 0 degrees Celsius is 18011.7 Joules.

2.20X10to the 4
Latent heat of fusion for H20 ice to water?
334 Joules per gram ... at 0oC, 334 Joules of energy must be added to melt one gram of ice from solid to liquid form, and 334 Joules of energy must be removed to freeze one gram of liquid water to form ice.
Can gum melt or does it shrivle in heat?
depends on the heat but usually it will melt
