Question

0°С тағы массасы 2 кг мұзды суға айналдыру үшін қанша жылу мөлшері қажет 8сынып

Answer 1

Дано:
m = 2 кг
λ=33*10⁶ Дж/кг - удельная теплота плавления льда
_______
Q - ?

Q=λ*m = 33*10⁶*2=66*10⁶ Дж или 66 МДж

Answer 2

I can understand and communicate in Kazakh. Your question is: Answer in detail. How much heat is needed to melt 2 kg of ice at 0°C? 8th grade.

To answer this question, we need to know the specific latent heat of fusion of ice, which is the amount of heat required to change 1 kg of ice at 0°C into water at 0°C. According to [one source](https://surak.baribar.kz/368155/), the specific latent heat of fusion of ice is 334 kJ/kg. This means that to melt 1 kg of ice, we need 334 kJ of heat. To melt 2 kg of ice, we need twice as much heat, or 668 kJ. Therefore, the answer is 668 kJ.

You can also use the formula Q = mL, where Q is the heat, m is the mass, and L is the specific latent heat of fusion. In this case, Q = 2 kg x 334 kJ/kg = 668 kJ. This formula is useful for calculating the heat needed to melt or freeze any substance, as long as you know its specific latent heat of fusion.
