Question

what type of thermal energy transfer occurs when a popsicle melts while you hold it outside on a sunny day?
conduction
convection
radiation

Explanation:

Thermal energy from the sun reaches the popsicle without direct contact. Conduction requires direct contact between materials, and convection involves the movement of fluids. Radiation is the transfer of energy by electromagnetic waves and can occur through a vacuum or space, like the sun - popsicle scenario.

Answer:

C. radiation
