We need to know the latent heat of fusion, L, for 0 degrees.
L = 336 kJ/kg, m = 2kg
where L is the latent heat for vaporization
Q = 2 * 336 = 672 kJ
For conversion between 0 and 100 degree Celsius
Q = mcθ, specific heat capacity = 4.2 kJ/kgK
Q = 2*4.2* (100 - 0) = 840 kJ
For conversion to steam at 100 degrees Celsius
<span>Q = mL , L = latent heat of vaporization = 2256 kj/kg
</span>
Q = 2 * 2256 = 4512 kJ
Total heat = 672 + 840 + 4512 = 6024 kJ
= 6 024 000 J
But 1 calorie = 4.2 J
Therefore 6 024 000 J will be: 6 024 000/4.2 ≈ 1 434 286 Calories
≈ 1 434 kCalories

Answer:
three properties of intrinsic semiconductor
Answer: The Sun measures 1.4 million km across, while the Moon is a mere 3,474 km across. In other words, the Sun is roughly 400 times larger than the Moon. But the Sun also happens to be 400 times further away than the Moon, and this has created an amazing coincidence.
