If the volume of a cube of wood is 15.625 cm3 and its mass is 10.00 g, show the calculation for the density of the wood.
d=m/v
m = 10.00
v = 15.625
10.00/15.625 = .64
.based on the density of the wood that you calculated above, would the wood float or sink if it is placed in a bowl of water? explain your answer. remember that the density of liquid water is 1.00 g/cm3

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg.how much energy e must be supplied to the device? express your answer in joules.
