Energy transfer is the process by which energy moves from one object or system to another. This can occur in various forms, such as heat, light, or motion. For example, when you touch a hot stove, thermal energy transfers from the stove to your hand, causing you to feel heat. Another common example of energy transfer is in photosynthesis, where plants convert sunlight into chemical energy. During this process, chlorophyll absorbs light energy, which is then transformed into glucose, providing energy for the plant's growth and development.
