    Calculating Heat of Vaporization for Ethyl Alcohol at 65°C

    Ok so I have: the BP= 78.5 C the specific heat = 0.58 kcal/kg and the heat of vaporization = 204 kcal/kg and 1 N = 1kg*m/s^2 I still don't know where to go with this. I'm in my first ever physics course and it is completely independent. Only notes I have to work with is the book and there is...

    Calculating Heat of Vaporization for Ethyl Alcohol at 65°C

    Homework Statement How many kilocalories of heat are needed to change 143N of ethyl alcohol at 65°C to vapour? Homework Equations Lv = Q/m The Attempt at a Solution I'm really stuck. I have no idea how to work the units of N with heat problems. I've looked online and in my book and have no...

    What is the magnitude of the force?

    Homework Statement Mike is training for a strongman competition. Using a rope, Mike is pulling a locomotive of mass 2.00 x 10^4 kg coupled to two 0.50 x10^4 kg rail cars. Mike causes the train to accelerate at 0.045 m/s^2 . What is the magnitude of the force in the coupling between the...
