The calorie is the unit of energy defined as the amount of energy needed to raise 1 g of water by 1 K. a. How many calories are required to bring a pot of water initially at 274 K to a boil? The pot is full to the brim, with a diameter of 20 cm and a depth of 20 cm. The density of water is 1000 g per cubic centimeter. b. If we consider that D for the pot...
Assuming that radiation with a wavelength = 15.0 cm is used, that all the energy is converted to heat, and that 4.184 J is needed to raise the temperature of 1.00 g of water by 1.00 degree celcius, how many photons are necessary to raise the temperature of a 350 mL cup of water from 25 degree C to 95 degree C?
1. Energy Units (6 points) 1) Calculate the amount of energy required to raise the temperature of 4 gallons of water from 50 degree F to the boiling point. A gallon of water weights 8.34 lb. Calculate the answer in three different energy units below. Show calculation. 1) BTU 2) calorie 3) Kwh 2) When heated by 300 BTUs, how many degrees (in F) will the temperature of 6 gallons of water increase? (3 points)
It takes 1 kcal to raise the temperature of 1 kg of liquid water by 1 C, but only 0.5 kcal to raise the temperature of 1 kg of ice or water vapor by 1 C. Also, it takes 80 kcal to melt 1 kg of ice sitting at 0 C, and 540 kcal to evaporate 1 kg of liquid water sitting at 100 C. 1) How much heat is required to melt 2 kg of ice at 0 C?...
9) How much energy in Kcal is needed to take 340 g of water at 6.0 degrees Celsius to steam at 127.0 degrees Celsius? ALSO indicate this process as a heating curve on the axes below. [the specific heat of ice, water and steam are 0.47, 1.00, and 0.48 cal/g oC respectively, Also the Heat of Fusion and Heat of vaporization of water are 80, and 540 cal/g respectively] You may or may not need all of these numbers. hny...
