The material defines Q, m, c, and ΔT, explains sign conventions for heating versus cooling, and emphasizes consistent units across heat and temperature scales. It includes water examples in calories and joules, comparisons across elements such as hydrogen and radon, an unknown material determination, and calculations for glass, mercury, and water cooling.","Name:   Block:   Date: / /   \nSpecific Heat Capacity Problems (644)  \nQ = mc\"T  \nWhere:  \nQ = heat (“Quantity” of heat; aka: Energy)  \nm = mass  \nc = specific heat  \nΔT = change in temperature  \nA few key ideas:  \n􀀡 If a substance receives heat and experiences an increase in temperature then Q is a positive number and ΔT is a positive number.  \n􀀡 If a substance loses heat and experiences a decrease in temperature then Q is a negative number and ΔT is a negative number.  \n􀀡 Q (heat energy) can be measured in either Joules or calories. Just make sure that your units for c are consistent with your units for Q.  \n􀀡 ΔT, change in temperature, can be measured in K, °C, or ° F. Just make sure that your units for c are consistent with your units for ΔT.  \n􀀡 Always start a problem by listing the given information (with units) and writing down the specific heat capacity equation (without plugging numbers in yet!)  \n􀀡 You must ALWAYS show all work and make sure you have consistent units on your final answer.  \n􀀡 The First Law of Thermodynamics states that if two substances exchange heat, the quantity of heat gained by one substance is exactly equal and opposite to the quantity of heat lost by the other substance.  \n􀀡 The specific heat capacity of water is:  \no cwater = 1 cal/(g° C) = 1 cal/(g⋅K)  \no cwater = 4.184 J/(g ° C) = 4.184 J/(g⋅K)  \no cwater = 4184 J/(kg ° C) = 4184 J/(kg⋅K)  \n1.
