Heating - GCSE Physics Definition

Heating, in the context of GCSE Physics, refers to the process of energy transfer that causes an increase in temperature in a substance or system. It occurs when thermal energy is transferred from a hotter object to a cooler one, typically through conduction, convection, or radiation. This process causes particles in the substance to move more vigorously, thereby raising the temperature. Heating is a fundamental concept in understanding how energy is exchanged and transformed in physical systems, and it directly relates to concepts such as specific heat capacity and changes in states of matter. Understanding heating processes is crucial for explaining everyday phenomena, such as why metal feels colder than wood at the same temperature or how kettles heat water.
