Text, Questions & Answers

Imagine holding a metal spoon in a hot soup. Ever noticed how the spoon gets hot? That's 'Conduction,' a type of heat transfer that happens between solid objects. Now, picture a pot of boiling water. The hot water rises, and the cooler water sinks, creating a circular motion. This is 'Convection,' which is heat transfer in liquids or gases. Finally, think about how you feel the warmth of the sun while standing outdoors. This is 'Radiation,' where heat transfer occurs without any contact! Heat transfer is magical, right? It's happening all around us, in everything from cooking food to weather patterns. Understanding it lets us make sense of many everyday phenomena and can even help us design better technologies.

Question 1
