A 245 g wooden cup at 18.5 C is filled with 419 mL of brewed coffee (essentially water) at 98.7 C. What will be the common final temperature (to three sig. figs.) of the cup and the coffee when thermal equilibrium is reached, if no heat is lost to the environment? ( specific heat of wood = 1695 J/kg.C)

    1)Brewed coffee is often too hot to drink right away. You can cool it with an ice cube, but this dilutes it. Or you can buy a device that will cool your coffee without dilution - a 200 aluminum cylinder that you take from your freezer and place in a mug of hot coffee. q)If the cylinder is cooled to -20C, a typical freezer temperature, and then dropped into a large cup of coffee (essentially water, with a mass of...

    PART A: A student constructs a coffee cup calorimeter and places 50.0 mL of water into it. After a brief period of stabilization, the temperature of the water in calorimeter is determined to be 19.6 °C. To this is added 50.0 mL of water that was originally a temperature of 54.5 °C. A careful plot of the recorded temperature established T0 as 31.1 °C. What is the calorimeter constant (J/°C)? DensityH2O = 1.00 g/mL Specific HeatH2O = 4.184 J/g·°C PART...
