Question

1.In the laboratory a student finds that it takes 214 Joules to increase the temperature of 14.9 grams of gaseous nitrogen from 24.8 to 39.5 degrees Celsius.
The specific heat of nitrogen calculated from her data is  J/g°C.

2.In the laboratory a student finds that it takes 66.2 Joules to increase the temperature of 12.6 grams of solid copper from 23.8 to 38.2 degrees Celsius.
The specific heat of copper calculated from her data is  J/g°C.

3.An electric range burner weighing 645.0 grams is turned off after reaching a temperature of 460.7°C, and is allowed to cool down to 23.1°C.
Calculate the specific heat of the burner if all the heat evolved from the burner is used to heat 599.0 grams of water from 23.1°C to 81.3°C.
Answer J/g°C
