Question

a boy places his hand near a glowing electric bulb without touching it and feels warmth. which type of heat transfer is responsible for the warmth he feels? convection radiation conduction insulation question 12 5 pts two metal containers are filled with ice and placed on a table. alicia wraps one container with cloth but leaves the other unwrapped. what is most likely to happen to the ice in the wrapped container compared to the unwrapped one? ice melts faster in the ______ container. question 13 5 pts true or false 1. cloth is a better insulator than metal foil. 2. metal foil is a better insulator than plastic film.

Explanation:

First Question (Heat Transfer Type):

Heat transfer via radiation occurs without a medium (like air, solids, or liquids) and can travel through empty space. A glowing electric bulb emits thermal radiation, so the warmth felt without touching is due to radiation. Convection needs fluid movement, conduction needs direct contact, and insulation is a heat - resisting method, not a transfer type.

Cloth is an insulator, which slows down heat transfer. The unwrapped metal container will absorb heat from the surroundings more quickly because metal is a good conductor. So ice in the unwrapped container will melt faster as it gains heat faster.

Answer:

radiation

Second Question (Ice Melting in Containers):
