17.4: Heat Capacity and Specific Heat - Chemistry LibreTexts

WebAnswer (1 of 4): I assume Q = mc(delta T) means that the heat flow equals the mass times the change in temperature times a “constant” (in this case, the specific heat). When you pump in heat, the temperature rises, as you would expect. The specific heat tells you how much the temperature will ri... WebSpecific heat is closely related to the concept of heat capacity. Heat capacity is the amount of heat necessary to change the temperature of a substance by 1.00 °C. In equation form, heat capacity C is C = m c, where m is mass and c is specific heat. Note that heat capacity is the same as specific heat, but without any dependence on mass. Webspecific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree. For example, the specific heat of water is 1 calorie (or 4.186 joules) per gram per Celsius degree. maggi powder
