B )When placed in water ( density 1 g/cc ) what is the Buoyant Force acting on the block and C ) What is its Weight in Water? 7) Convert the Following Temperatures : a. -40 OC to OF b. 0 OF to C and K c. Normal Body Temp of 98.6 OF to C and then K d. The Moon's range of Temps of a High of 375 K to a low of 100 K to both .C and OF 8) A 0.09 kg mass with an initial temperature of 100 C is placed in an insulated cup of water with mass of 0.6kg water initially at 180C. If the final temperature of the whole system - mass and water only - reaches equilibrium at 23C what is the Specific Heat Capacity of the mystery metal mass ( note water specific heat capacity is 4186 J/kg*oC )
