Answer:
The needed energy to melt of ice is 1670 J.
Explanation:
Given that,
Mass of ice = 5 g
Specific latent heat = 334000 J/kg
We need to calculate the energy
Using formula of energy
Where, m = mass
L = latent heat
Put the value into the formula
Hence, The needed energy to melt of ice is 1670 J.
Answer/Explanation:
Energy is a resource important to all people, but some energies are expensive and can be used only once, like the fossil fuels in gas. With renewable energy the united states could save money without being wasteful with our supplies on earth. so it is no wonder why the U.S is gaining attention on it.
