QUESTION: 1

Thermal conductivity of water in general with rise in temperature

Solution:

QUESTION: 2

Thermal conductivity of air with rise in temperature

Solution:

QUESTION: 3

Heat is mainly transferred by conduction, convection and radiation in

Solution:

Because for radiation to be comparable the magnitude of temperature difference should be large enough, Convection & conduction is also predominant in boiler furnace.

QUESTION: 4

Heat conduction in gases is due to

Solution:
QUESTION: 5

Heat transfer by molecular collision in

Solution:
QUESTION: 6

Arrangement of silver, air, aluminium and lead in order of increasing thermal conductivity at room temperature yields

Solution:

According to their thermal conductivity for Air, k = 0.022 W/mK
for Aluminium, k = 205 W/mK
for Silver, k = 407 W/mK
Hence correct sequence is
Air, Lead, Aluminium, Silve

QUESTION: 7

Metals are good conductors of heat because of

Solution:
QUESTION: 8

Choose the correct statement about thermaf conductivity

Solution:

Due to increase in lattice vibratioh the thermal conductivity of metals decreases with increase in temperature.

QUESTION: 9

Cork is used as a good insulator

Solution:
QUESTION: 10

In which one of the following materials, is the heat energy propagation minimum due to conduction heat transfer

Solution:

Since thermal conductivity of air is minimum among the given material hence heat transfer will be minimum in air.
