Question

how is thermal energy being transferred when steam rises from a beaker of boiling water?
a. convection
b. conduction
c. radiation
d. translation

Explanation:

To determine how thermal energy is transferred when steam rises from boiling water, we analyze the heat transfer methods:

• Convection involves heat transfer by the movement of fluids (liquids or gases). When water boils, the hot, less - dense steam (a gas) rises, carrying thermal energy with it. This is a classic example of convection.
• Conduction requires direct contact between particles and is more common in solids (e.g., heat moving through a metal spoon in hot soup). Since steam rising is the movement of a gas, conduction is not the main process here.
• Radiation is heat transfer via electromagnetic waves (e.g., heat from the Sun). There is no electromagnetic wave - based heat transfer involved in steam rising from boiling water.
• Translation is not a recognized method of heat transfer.

Answer:

A. Convection
