It looks like you are trying to describe the three methods of heat transfer: convection, conduction, and radiation. I'll help you complete and clarify each section.
Convection
- Definition: Heat is circulated through fluids such as air or water.
- Example: Soup heating in a pot because the hot soup rises while the cooler soup descends, creating a circulation of heat. When the soup rises and cools down, it sinks again, continuing the cycle.
Conduction
- Definition: Heat that moves through an object or between objects that are in direct contact with each other.
- Example: A frying pan on the stove heats up because heat from the burner is conducted through the metal of the pan to the food inside it.
Radiation
- Definition: Heat that is transferred through electromagnetic waves between two objects that are not touching.
- Example: A hand near an open flame can feel the heat because radiation from the flame travels through the air and warms the hand without direct contact.
If you need any further clarification or additional examples, feel free to ask!
