Q heat physics
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. The Scottish scientist Joseph Black, in the 18th … WebWhen heat energy is added to a substance, the temperature will change by a certain amount. The relationship between heat energy and temperature is different for every material, and the specific heat is a value that describes how they relate. heat energy = (mass of substance) (specific heat) (change in temperature) Q = mc∆T
