The energy that is lost by the coffee and the mug is being transferred to the colder surroundings. We refer to this transfer of energy from the coffee and the mug to the surrounding air and countertop as heat. In this sense, heat is simply the transfer of energy from a hot object to a colder object.
The thermal surroundings exchange energy with a system in the form of heat. The floor is the thermal surroundings in Figure 3.3. The faster the system (mass M) hits the floor, the greater is the amount of energy that is transferred to the thermal surroundings.The mechanical surroundings exchange energy with a system in the form of work. The red mass m is the mechanical surroundings in Figure 3.3.hapter 3 The First Law of Thermodynamics 81 water, which is related to the specific heat and mass of the water by the following (see Equation 3.2): C cal ~ m water s water Substitution of the above into Equation 3.14 yields the common approximation of the calorimetry equation.
