Question

ironing a shirt is an example of...
condensation
convection
conduction
radiation

Explanation:

When ironing a shirt, heat is transferred directly from the iron (a hot object) to the shirt (a cooler object) through direct contact. This is the definition of conduction. Condensation is the change of gas to liquid. Convection involves heat transfer through fluid (liquid or gas) movement. Radiation is heat transfer via electromagnetic waves (like the sun's heat reaching Earth).

Answer:

conduction
