Two cups of coffee, one that is at 10°c and one that is at 20°c, are mixed. which statement about the temperature of the mixture is correct? '

a. there is no kinetic energy transfer so the temperature of the coffee in the warmer cup is the final temperature.
b. the kinetic theory dictates that the temperature of the coffee in the cooler cup is the final temperature.
c. energy is transferred from faster moving molecules to slower moving molecules, and the result is the average of 15°c.
d. energy transfer occurs as the molecules collide, and the result is additive; the final temperature is 30°c.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
