I am trying to calculate energy change, but I am lost. = - (100 grams)x(4.184 Joules/degrees Celsius x grams)x(-6.1 degrees celsius)
What mass in grams of aluminum fins could 2423 Joules of energy heat from 13.14 degrees Celsius to 23.05 degree Celsius? Aluminum has a specific heat of 0.897 Joules(g times degrees Celsius)
you decided to investigate how much energy it would take to get solid acetone to gaseous acetone. So assuming you took 125 g of -100 degree Celsius solid acetone and heated it 56 degree Celsius gaseous acetone, how many joules of energy would be required to do this? Acetone has a melting point of -95 degree Celsius and a boiling point of 56 degrees Celsius. The heat of fusion (melting) is 98 j/g and the heat of vaporization is 538.9...
