Question

In the laboratory a student finds that it takes 77.4 Joules to increase the temperature of 14.1 grams of solid copper from 24.6 to 39.9 degrees Celsius.

The specific heat of copper calculated from her data is ______ J/g°C.

Answer 1

Hello, Omar,

I just responded to a similar problem. Please see that answer for a few more of the details on how these types of questions can be answered.

I'm letting the units guide me. I want specific heat in J/gC.

77.4 Joules/((14.1 grams)(15.3C)) = 0.259 J/gC (3 sig figs)
