شرح ساينس الصف الرابع الابتدائي لغات - الفصل الدراسي الثاني شرح ساينس رابعة ابتدائي - ترم ثاني n: How does energy change (transform) ? Device Consumed energy (Input energy) Produced energy (Output energy) Hair dryer Electrical energy. Thermal energy and sound energy. Soap dispenser Potential energy (stored in the spring of the soap dispenser). Kinetic energy (The movement of the soap upward). Washing machine Electrical energy. Kinetic energy and sound energy. When you rub your hands, you will feel warm because kinetic energy (consumed energy) is converted into thermal energy (produced energy). Energy Chains Energy chain is a way to describe or represent the energy flow that occurs when we use different devices. Energy chains often start with the Sun . • Now, we will study some examples of energy chains. Energy chain when eating food Energy chain when heating a pot of water over a fire Energy chain in a hair dryer n: How does energy change (transform) ?
