1.First, don't try that at home, it won't work or be pleasant. That aside, let's pretend you take a bottle of pure ethanol at room temperature (23 degrees Celsius) and proceed to heat it up until you produce gaseous ethanol at a temperature of 85 degrees Celsius. Assuming the ethanol in the bottle had a mass of 250 grams, how many joules of energy was required to do this? The heat of vaporization of ethanol is 841 j/g and its...

A 2kg block of ice at 0 degrees celsius is dropped into a very large lake at 25 degrees celsius and completely melts. For water, the heat of fusion is 3.35*10^5 J/kg, the heat of vaporization is 2.25*10^5 J/kg, and the specific heat is 4190 J/kg*K. What is the net change in entropy of the system consisting of cie and the lake due to this melting process?

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...

The heat energy associated with a change in temperature that does not involve a change in phase is given by -msAT where q is heat in joules, mis mass in grams, s is specific heat in joules per gram-degree Celsius, J/(g·°C). and AT is the temperature change in degrees Celsius. The heat energy associated with a change in phase at constant temperature is given by where q is heat in joules, m is mass in grams, and ? H...

Your 200g cup of coffee is boiling hot (100 degrees celcius). You throw in 50g of -15 degrees celcius of ice to cool it off. Assuming negligible heat leaves the coffee-ice system during this process, what is the final temperature of your coffee? (The specific heat capacity of ice is 2.03 J/(g degree C and the specific heat capacity of water is 4.18 and the latent heat of melting for ice to water is 334J/g).
