In this chapter, we explore heat and temperature. It is not always easy to distinguish these terms. Heat is the flow of energy from one object to another. This flow of energy is caused by a difference in temperature. The transfer of heat can change temperature, as can work, another kind of energy transfer that is central to thermodynamics.
Heat and temperature are two different but closely related concepts. Note that they have different units: temperature typically has units of degrees Celsius (∘ C ) or Kelvin (K ), and heat has units of energy, Joules (J ). Temperature is a measure of the average kinetic energy of the atoms or molecules in the system.
Temperature and heat are not the same thing: temperature is a measure of how hot something is. heat is a measure of the thermal energy contained in an object. Temperature is measured in...
Heat is driven by temperature differences, while work involves a force exerted through a distance. Nevertheless, heat and work can produce identical results. For example, both can cause a temperature increase. Heat transfers energy into a system, such as when the sun warms the air in a bicycle tire and increases the air’s temperature.
The equation that relates heat, specific heat capacity, mass, and change in temperature is where is the heat (measured in calories), is the mass (measured in grams), is the specific heat capacity, and is the temperature change (measured in degrees Celsius).
