Question

In the laboratory a student finds that it takes 69.0 Joules to increase the temperature of 12.8 grams of solid chromium from 22.1 to 35.0 degrees Celsius. The specific heat of chromium calculated from her data is J/g°C.

Answer 1

To calculate the specific heat of chromium, you can use the formula:

Specific Heat = Energy / (Mass * Temperature Change)

In this case, the energy is 69.0 Joules, the mass is 12.8 grams, and the temperature change is 35.0 - 22.1 = 12.9 degrees Celsius.

So, the specific heat of chromium can be calculated as:

Specific Heat = 69.0 J / (12.8 g * 12.9 °C) = [calculate the value] J/g°C
