Efficient Energy Transfer: IGCSE Coordinated Science Perspective

IGCSE Coordinated Science: Consequences of Energy Transfer Consequences of Energy Transfer 1. Identify and explain some of the everyday applications and consequences of conduction, convection and radiation. In our everyday environment, conduction, convection, and radiation are constantly taking place. They have many applications and can be very useful, some examples include: ● When we heat up pots and pans, the thermal energy is transferred through conduction ● Air condition uses convectional currents to cool the indoor environment. ● When heating up water, the heat is applied from below so it creates a convectional current, which heats up the whole body water ● Sea breezes are caused by convectional currents. This is due to the difference between the temperature of the sea and land. ● Radiation enters greenhouses through the glass and the heat is absorbed and trapped to maintain the temperature ● Solar panels produce electricity by absorbing the heat from sunlight by radiation
