    Calculating Change in Entropy for Water Vaporization at 100oC

    Homework Statement The latent heat of vaporization for water is 540 kcal/kg. By how much does the entropy of 50g of water at 100oC change if the water is very slowly converted into steam at 100oC? Homework Equations The Attempt at a Solution would it be 0 heat change plus the 540...

    Buoyancy problem answer check. Thanks

    Homework Statement A 2.5 kg block of wood is floating in water. What is the magnitude of the buoyant force acting on the block? Homework Equations The Attempt at a Solution m=2.5kg b=mg=2.5*9.81 b= 24.5N Is this right? Thanks in advance for the help!
