Question
Surces of error in the experimental procedures. If the to the calorimeter in the heat-of-fusion experiment were less I. Discuss the most important f the ice added temperature o this affect the results? Why should you use small picces of ice rather than large pieces? 2. Explain why burns caused by steam at 100°C are more serious than those caused by an equal mass of boiling water at the same temperature. 3. How is the latent heat of water used in the cooling mechanism of our bodies? 4. What is the heat of sublimation? [Hint: Dry ice (solid CO.) sublimes.JExplanation / Answer
2.
This is because the heat contained by steam at 100 C is greater than the heat contained by water at 100 C. due to this more heat , the burn caused by steam more severe
3.
To evaporate, the drop of sweat on our body absorbs energy from the body. as the heat is aborbed from the body , the body cools down
4.
at given temperature and pressure , the heat required to to change the phase from solid to gas is called heat of sublimation
