Question

1. it is a cold, snowy day. paul and his family are inside a wood - cabin. it is snowing, it is cold outside, and inside the cabin it isnt much warmer. paul can hear the wind howling down the chimney. \paul, help me build a fire.\ paul fetches the kindling and then watches as his father carefully stacks the logs in the shape of a pyramid. pauls father puts several small sticks of kindling in the bottom of the pyramid. the kindling would catch on fire much sooner than the big logs. pauls father lights a match, and soon the logs crackle and burn in the fireplace, shooting off small sparks. the fire glows off warm light, but it also gives off heat. within 30 minutes the air throughout the cabin is warm and toasty. which method of heat transfer did not contribute to the warming of the cabin? (a) conduction, convection, and radiation (b) conduction (c) radiation and convection (d) radiation

Explanation:

Conduction is the transfer of heat through direct contact. In the cabin - building scenario, when the logs are stacked and the fire is lit, heat is transferred from the fire to the surrounding logs by direct contact (conduction). There is no mention of heat transfer by the movement of fluids (convection) or heat transfer through electromagnetic waves (radiation) in the warming of the cabin in the given text.

Answer:

B. conduction
