Answer:
Energy is the ability to do work or produce heat. Heat is commonly measured in units of calories. One calorie is equivalent to 4.184 joules. Another unit for heat is the Calorie, which is equal to 1000 calories or 4184 joules. The amount of heat required to raise the temperature of one gram of a substance by one degree Celsius is called specific heat capacity. The equation needed to calculate the amount of heat released or absorbed during a temperature change is Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the temperature change. In this formula, ΔT is calculated by subtracting the initial temperature from the final temperature of a substance and has the following units: Celsius or Kelvin. The answer will be positive if heat is absorbed and negative if heat is released.
