2. Suppose a piece of metal at 90 °C is quickly transferred into a Styrofoam cup containing 212 grams of water at 24 °C. After a minute or so, the temperature of the contents of the cup is stable at 35 °C. Use 4.2 J/(g.°C) as the specific heat capacity of water and assume that during this time the energy transferred between the contents of the cup and the surroundings is negligible and that there is no heat loss to the cup. (a) How much heat in joules is gained by the water? (b) How much heat in joules is lost by the metal? (c) What is the heat capacity of this piece of metal? (d) If the mass of the metal is 196 grams, what is its specific heat capacity? (e) What is the change of water's entropy? Note the volume of water stays the same. (f) What is the change of total entropy of the system, including both water and metal?

dsphere dbar • Given the above system, two spheres attached to the ends of a cylinder, determine the mass moment of inertia about the axis normal to the page as a function of the variables provided. Note, you can treat the masses of each element of the system as known o (msphere and mbar). After deriving an expression for the mass moment of inertia about the axis normal to the page as a function of the variables, calculate the mass moment of inertia given: osphere properties ▪ mass of sphere = 5 kg 1 diameter of sphere = 0.5 m bar properties ▪ • Determine the resultant force and moment acting on the system if the system is moving as follows: mass of bar = 25 kg length of bar = 7.5 m diameter of bar = 0.25 m O a = 5î+ 2ĵ m/s² O αG = 7k rad/s² ασ
