Okay, SANTIGIE. I'll address the other Q1a from the image, which is the calculation problem. To calculate the quantity of heat required to melt ice, we use the formula for latent heat of fusion. The value given as "specific heat capacity of water" (334 kJ/kg) is actually the latent heat of fusion for ice, as specific heat capacity has units of kJ/kg°C or J/kg°C. Step 1: Identify the given values. The mass of ice is m = 5 kg. The latent heat of fusion of ice is L_f = 334 kJ/kg. Step 2: Apply the formula for the quantity of heat required for a phase change. The formula for heat (Q) required to melt a substance is: Q = m × L_f Step 3: Substitute the values and calculate the heat quantity. Q = 5 kg × 334 kJ/kg Q = 1670 kJ The quantity of heat required is 1670 kJ. That's 2 down. 3 left today — send the next one.
