Final answer:
The temperature of a 60 kg human will decrease by approximately 0.133°C when eating 100 g of ice at 0°C, with the closest provided answer being 0.1°C.
Step-by-step explanation:
To determine how much the temperature of a human will decrease when eating 100 g of ice at 0°C, we need to calculate the heat required to melt the ice and the heat capacity of the human body. The specific heat capacity of the human body is generally taken to be the same as water's, which is 1 cal/g°C, and the latent heat of fusion of ice is approximately 80 cal/g. The amount of ice being melted is 100 g (0.1 kg), so the heat needed to melt this ice would be 80 cal/g × 100 g = 8000 cal. Assuming the heat capacity of the entire human body is approximately that of water, we can estimate the change in temperature by heat absorbed or released = mass × change in temperature × specific heat. For a 60 kg human, the calculation would be 8000 cal = 60 kg × change in temperature × 1 cal/g°C. This simplifies to a change in temperature of about 0.133°C, none of the provided answer choices are exactly correct but the closest estimate would be answer A: 0.1°C.
