An object that falls from the roof of a building starts with potential energy that becomes kinetic energy as the object falls. When the object strikes the ground, some of the kinetic energy is dissipated into the atomic-level motion of the particles that make up the object, and its temperature increases. If a 1.10 kg piece of iron fell from the roof of a building that was 26.0 m tall, what is the maximum temperature change (in °C) that it could experience? (In practice, the temperature change would be much less than this because a significant amount of
Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.
