Chemistry/Physics General Thermodynamics?

Question

Your 300mL cup of coffee is too hot to drink when served at 88.0. degrees Celsius.

What is the mass of an ice cube, taken from a -17.0 degrees Celsius freezer, that will cool your coffee to a pleasant 58.0 degrees C?

Answer 1

use the equation m = (s (delta t))/q
where m = mass s = specific heat delta T = temperature change
and q = heat.

I think.... only do this if this makes sense to you. I did not ACE that section...

Answer 2

Use specific heat, dm/dT
