Determine the amount of heat that must be added to raise the temperature of a cup of coffee ( 50.0 mL ) from 20.5ºC to 95.6ºC . Assume that water and coffee have the same density (1.00 g/mL) and same specific heat capacity ( 1 cal /g·°C).

Question

Determine the amount of heat that must be added to raise the temperature of a cup of coffee ( 50.0 mL ) from 20.5ºC to 95.6ºC .  Assume that water and coffee have the same density (1.00 g/mL) and same specific heat capacity ( 1 cal /g·°C).

DrBob222 · Answer

q = heat needed = mass coffee x specific heat coffee x (Tfinal - Tinitial)
Substitute and solve for q. Tfinal is 95.6 from the problem. Tinitial is 20.5 from the problem. Post your work if you get stuck.

Rich · Answer

So it will be.. Q = (50.0mL) X (1cal) x ( 95.6 - 20.5) = Is this the right set? @DrBob222
