I would say that as 1 calorie raises the temp of 1 cubic cm or 1g of water by 1 degree that you would need 25 calories to raise 25g of water to 1 degree c therefore melting it.

1 calorie is 4.18 Joules\n1000 is 1 kilo\nThe ratio is always 4.18:1\nso... 1 kilocalorie=4.18 kilojoules

Look at your units for latent heat. Joules per g. That means it takes 334 J to convert each gram of ice to liquid water. You have 250 g of ice. That should tell you what the formula is.

Easy.  \n\nYou have q = mass * specific heat * change in temp.\n\nFind the specific heat of water and your set.  Q is joules so you need to convert.

there an equation H= mass ( in kg)* 4.2 (for water) change in temp ( in degree ~C)\n\nso \n\nH = 40*4.2* 20\n\n\ni think its 3360 J\n\n\nthe guy above is correct except the mass is kg to cancle the Cp units of  J / kg C

Although I know I am not getting this $20.  199 kJ of energy.\n\nIn response to a later answer that claimed I was wrong he was right and wrong\n\n He wrote "first find the amount of mol of nitrogen\nmol = 1/14" But infact the amount was 1 kg and that divided by 14g/mol would be 71.43 moles and multiplying that times his enthalpy of vaporization which is 2.7928kJ/mol would give 199 kJ of energy. So I was right, but wrong with my significant figures because the asker said it was 1.0 kg which would gie me 2 sig figs and the answer would be 2.0*10^2 kJ.

mcdelta theta\nm=1 kg(by default)\nc=4.2 J/degree/kg\ndelta theta= 75\ne=1*75*4.2\n  =315 j

To convert between g and kg you just need to know that 1 kg = 1000 g.  If you know your metric conversions, these become very easy!  One "kilo" of anything is 1000 of that base unit.  So 1000m = 1 km as well.  So to find out how many grams 8.2 kg is just think: \n\n8.2 kg X (1000 g/ 1 kg) = 8,200 g

It's not, that is only a certain method of measuring a calorie.  A calorie is the amount of energy required to raise the temperature of 1 gram of water 1 degree celsius at 1 atmospheric pressure.  \n14.5 and 15.5 (celsius) are merely the temperatures chosen to start and end at.  There is also the 20 degree calorie (19.5-20.5) and 4 degree calorie (3.5-4.5). The differences in energy required from different temperatures vary in the thousandths of a joule.

Multiply kilos by 2.2 to get pounds. Multiply pounds by .454 to get kilos.

Kangaroos Hop Down Under drinking chocolate milk - this gives you the order\n\nK = kilo\nH = hecto\nD = deca\nU = unit (meter, liter, gram, etc)\nd = deci\nc = centi\nm = milli\n\nso start with what you are given, 10 meters would start on the U.  Move to the H for hecto - you had to move to the right 2.  So move your decimal point 2 to the right.  10 -> 1.0 -> .10.  There are .10 hetometers in 10 meters.

Think of a gram as being the "base" unit. \nThe prefix kilo means 1,000. In other words, 1 kilogram = 1,000 grams.\nTo convert from grams to kilograms, simply move the decimal point 3 places to the left.\nExamples:    18.6 grams  =  .0186 kilograms\n            5,698 grams  =  5.698 kilograms\n\nTo convert from kilograms to grams, move the decimal point 3 places to the right.\nExamples:    89.4 kilograms   =   89400.0 grams\n             0.939 kilograms  =   939.0 grams\n\nThe prefix "milli" means 1/1000.  In other words, a milligram is 1/1000 of a gram. To convert grams to milligrams, simply move the decimal point 3 spaces to the right.\nExamples:   45.0 grams  =  45,000.0 milligrams\n           0.98394 grams  =  983.94 milligrams\n\nTo convert milligrams to grams, move the decimal point 3 places to the left.\nExamples:    678.0 milligrams  =  0.678 grams\n             7,233.0 milligrams  =  7.233 grams\n\nThe prefix "micro" means 1/1,000,000.  In other words, a microgram is 1/1,000,000 of a gram.  To convert grams to micrograms, simply move the decimal point six places to the right.\nExamples:  45.0 grams  =  45,000,000.0 micrograms\n           0.98934 grams  =  989,340.0 micrograms\n\nTo convert micrograms to grams, move the decimal point six places to the left.\nExamples:  67,823.0 micrograms  =  0.067823 grams\n           456.0 micrograms  =  0.000456 grams\n\nConverting liters, milliliters, microliters, etc., is done the exact same way. Just substitute the word "liter" for the word "gram".\n\nTo convert pounds to kilos:\n\nDivide the number of pounds by 2, then subtract 10%. This is the generally accepted way to do the conversion in the medical field.\nExample:       160 pounds\n               = 80 when divided by 2\n               10% of 80 is 8\n               80 - 8 = 72 kg\n\n               192 pounds\n               = 96 when divided by 2\n               10% of 96 is 9 (you drop anything after the \n                               decimal)\n               96 - 9 = 87kg\n\nI hope this helps. Post another question if you need more help.  Good luck.

Q (heat energy) = m(mass in gram)*c(specific heat in J/gm/K)*t (change in temp)\nQ = 25 * 1 * (36-24)\nQ = 300 J

Your reaction evolved 500 calories (you raised 100 grams of water five degrees) , or 500*4.184 J = 2092 Joules.\n= 2.092 kJ\n\n\n2.092 kJ / 0.05225 mol = 40.0 kJ/mol

You want "energy density:"\n\nEthanol (Ethyl Alcohol):\n26.8 MJ / kg\n= 2905 kCal / lb.\n\nCrude Oil:\n45 MJ / kg\n= 4879 kCal / lb\n\nAviation Kerosene:\n43 MJ / kg\n= 4662 kCal / lb\n\nI don't understand the "If measured with a calorimeter, what degree celsius would it reach." Are you talking about the combustion temperature?
