Question

NEED ASAP!! Alex studied the image shown below. He concluded that the image shows thermal energy being transferred from the flames to the person’s hands through the process of conduction. Which best explains Alex’s error? *
1 Thermal energy is being transferred from the person’s hands to the flames.
2 The hands need to be in direct contact with the flames to have conduction.
3 Thermal energy can only be transferred through radiation with flames.
4 The hands need to be above the flames without touching them to have conduction.
5 The process of conduction cannot happen with flames.

Answer 1

Answer: 2

The hands need to be in direct contact with the flames to have conduction

Explanation:

A fire spreads by transferring  heat energy in three ways: Radiation, Convection, and Conduction. Radiation by emitting energy in rays or waves.  Heat moves through space as energy waves by conduction. As the fire front gets closer, the amount of radiant heat received is increased.

Heat energy in the form of electromagnetic radiation moves away from a hot object in all directions. Radiant heat is particularly important to fire development in a compartment in that it serves as one of the primary mechanisms for fire spread within the compartment.
