Question

1. whether watching water boil or sitting by a campfire, heat energy travels in one of three ways: conduction, convection, or radiation. determine the method of heat energy transfer for each scenario in the table.

Explanation:

• An egg frying in a pan: Heat is transferred through direct contact between the pan and the egg, which is conduction.
• Feeling the heat of the Sun: Heat travels from the Sun to Earth through electromagnetic waves (without a medium), which is radiation.
• Touching a hot bowl of soup: Heat is transferred by direct contact, which is conduction.
• A hot air balloon floating: Hot air (less dense) rises and cooler air (more dense) sinks, creating a circular motion. This is convection.
• Warming up next to a heater: The heater warms the air around it, and the warm air rises (convection current), which is convection.

Answer:

• An egg frying in a pan: Conduction
• Feeling the heat of the Sun: Radiation
• Touching a hot bowl of soup: Conduction
• A hot air balloon floating: Convection
• Warming up next to a heater: Convection
