Question

An experiment is completed where coal is burned in order to heat water and determine the specific heat capacity of coal. q = mcAT a. Water has a specific heat capacity of 4.184 J/g °C. The experiment heated 200 grams of water from 30°C to 100°C. How much energy is absorbed by the water? b. Assume the experiment is a closed system. The experiment used 170 grams of coal and the temperature change is 30°C to 252°C. What is the specific heat of coal?​
