How much energy is needed to reduce water temperature from 15 degrees to 14 degrees?
1 calorie increases 1 gram of water by 1 degree celsius. 4.18 Joules are needed to increase the temperature of 1 gram of water by 1 degree celsius. To reduce the 1 gram of water 1 degree celsius it would have to give off 1 calorie of energy. To calculate the energy multiply the mass in grams of water by 4.18 and by the change in temperature. The energy = 4.18 x m x change in T. The answer is in Joules. If you are using calorie as the unit of energy, replace 4.18 J by 1 C. Note that food is measured in kilocalories (Calories) not metric calories.
What is the air temperature when it snows or sleets?

How many kilocalories of heat are needed to raise the temperature of a 38.9 g sample of aluminum metal by 83.7Celiues?
It is dH = m C dT dH = 225 ( 0.21cal/gram-C) (80 C) 3780 calories your answer: 3.8kcal
Does ice melt and boil at specific tempurtures?
Yes, usually water will melt at anything above 0 degrees celsius or boil at 100 degrees. However pressure and altitude can change the required temperature needed for boiling/melting. The higher pressure the lower temperature required and vice versa The higher altitude the less temperature needed

4 kg of ice at 0 degrees Celsius is converted to steam at 100 degrees Celsius How much heat is needed?
It takes 80 calories per gram to increase the temperature of water by one degree. 4000 * 80 * 100 = 32000000 calories.
