Calculate the total heat capacity?
Okay, I need help on part b on my practice midterm. The question is: In order to wake up in the morning, I pour 4 shots of espresso coffee (35.0mL each) at 92.0 C into a cup 315 mL of lukewarm (last night) coffee (37.8 C).
a. Calculate the final temperature of my coffee; assuming that the specific heat and density of the coffee is independent on the brew? I got 54.476 C (which is correct)
b. When the coffee is poured into a coffee mug that sits at room temperature, the final temperature drops by 2 C. Calculate the total heat capacity of the coffee mu

Best ResponseYou've already chosen the best response.0My prof gave me a few hints about part b, and said that since I didn't have the mass of the coffee cup it would essentially be counted as 1 unit. Now how do I find the specific heat of the coffee?

Best ResponseYou've already chosen the best response.0assume it's the same as water, as the coffee will be a very small percentage of the total.
