Quizplus · Accepted Answer

When ice melts into water, it undergoes a change in phase from solid to liquid, which requires energy in the form of heat. The amount of heat required to melt the ice can be calculated using the formula:

Q = mL

where Q is the heat absorbed by the ice, m is the mass of the ice (1 kg in this case), and L is the latent heat of fusion of water (334,000 J/kg).

Thus, plugging in the values, we get:

Q = 1 kg x 334,000 J/kg = 334,000 J

Therefore, the amount of heat absorbed by the ice as it melts is 334,000 J, which is option E.

Specific Heat Capacity of Ice = 2,000 J/kg-°C Latent
