How much latent heat is needed to completely melt 368 gram ice cube?
To find out how much latent heat is needed to completely melt a 368 gram ice cube, you need to know the specific latent heat of fusion of ice.
The specific latent heat of fusion refers to the amount of heat energy required to change the state of one gram of a substance from solid to liquid at its melting point, without changing its temperature.
For water, the specific latent heat of fusion is approximately 334 joules per gram (J/g).
To calculate the amount of latent heat needed, you can use the following formula:
Latent heat = mass × specific latent heat of fusion
So, to find out the amount of latent heat needed to completely melt the 368 gram ice cube, you can multiply the mass by the specific latent heat:
Latent heat = 368 g × 334 J/g
Latent heat = 123,312 joules
Therefore, approximately 123,312 joules of latent heat are needed to completely melt a 368 gram ice cube.
