How does energy transfer between objects? Use an example to explain this.

Answer 1

Energy transfer between objects occurs through various mechanisms such as conduction, convection, and radiation.

For example, consider a pot of water sitting on a stove. When the stove is turned on, it heats up the bottom of the pot through conduction. The molecules in the bottom of the pot gain kinetic energy and start moving faster, transferring heat energy to the water molecules above them through conduction as well. As the water molecules gain energy, they start moving faster and expand, becoming less dense. This causes them to rise towards the surface of the pot in a process known as convection, transferring heat energy from the bottom to the top of the pot. Finally, some of the heat energy is transferred from the pot to the surrounding air through radiation, as the hot pot emits infrared radiation that warms up the air in its vicinity.

In this example, energy is transferred between the stove, the pot, the water, and the air through the processes of conduction, convection, and radiation. Ultimately, the heat energy is distributed and transferred among these objects until thermal equilibrium is reached.

Answer 3

When you cook soup on the stove, the heat from the fire makes the pot hot. The hot pot then makes the soup hot by touching it. This is called conduction. Then, the hot soup rises up to the top of the pot because it gets lighter and mixes with the cooler soup. This is called convection. Some of the heat from the pot also goes into the air around it, making the kitchen warmer. This is called radiation. So, the soup gets heated up because the pot and the soup and the air are all sharing the heat energy!
