539 calories per gram for heat of vaporization plus 1 cal/gram/degree C
100 degrees C - 80 degrees C = 20 degrees C
(539 calories + 20 calories) X 50 kg X 1000 gm/kg = 27950000 cal = 27,950 kcal

q( in Joules ) = mass * specific heat * change in temp.
q = (5000 grams)(4.180 J/gC)(100 C - 20 C)
= 1672000 Joules
Now, 4.184 Joules = 1 calorie, so....
1672000 Joules (1 calorie/4.184 Joules)
= 399617.59 calories ( you do significant figures )

∙ 13y agoEnergy = mass x specific heat capacity x change in temperature
The specific heat capacity(the energy required to raise 1 kg of a substance by 1 degree Celsius) of water is around 4200 Joules per kilogram per degree Celsius. The change in temperature is 100- 80 = 20 degrees Celsius.
Energy = 50 x 4200 x 20 = 4.2 x 105 Joules

How many joules of energy are needed to heat steam from 100 celsius to 114 celsius?
Approx 2940 Joules.
How much heat energy in kilojoules is required to convert 68.0 g of ice at 18.0 to water at 25.0?
It requires 1 calorie to increase 1 mL of water by 1 degree Celsius. In 68 grams of water, there are 68 mL. The change in temperature is 7 degrees, so 476 calories are needed. 1 calorie has 4.184 joules, hence 1.992 kJ are needed.
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 property of a material tells you how much energy it can store?
Specific heat capacity tells you how much stuff energy can store. specific heat capacity is the amount of energy needed to raise the temperature of 1kg of a substance by 1 degrees celsius. water has a specific heat capacity of 4200 J/kg degrees celsius.
How many joules are needed to change the temperature of 100 g of water from 20 degrees Celsius to 40 degrees celsius?
8.200 J
How many calories are needed to heat up 5 grams of water by 3 degrees Celsius?
(5)(3)= 15 calories. 1 calorie is the energy (heat) to raise 1 gram of water by 1 degree celsius, so 5 grams of water (3 degrees Celsius) = 15.
O degrees Celsius should be transferred to the temperature of absolute zero what is your comment to this statement?
its not needed as it is quite easy to convert Celsius to the Kelvin temperature scale, witch parralels the Celsius scale. subtract 273.15 from celcius to get to kelvin, and 0 is absolute zero on the kelvin scale.
