Topic : Flow of Heat
Very Short Question/Answers-
Question 1 By which mode is heat transferred in solids?
Answer : In solids, heat is transferred through the process of conduction. This is because the molecules in solids are rigid and only vibrate on heating rather than moving from one place to the other. The vibrating molecules of the hotter region hit those molecules in the colder region, causing the transfer of heat.
Question 2: Are most metals good or bad conductors of heat?
Answer : Most metals are good conductors of heat. This is because the molecules in metals vibrate and hit the nearby molecules to transfer the heat energy, rather than moving from one place to the other.
Question 3: Gases are insulators of heat. True of false?
Answer : True Gases are insulators of heat because their molecules are loosely bonded; hence, they do not conduct heat.
Question 4: By which mode is heat transferred in liquids?
Answer : Heat transfer in liquids takes place through the process of convection. In this case, the molecules of liquids move from one place to other to transfer the heat energy.
Question 5: Name a liquid which is a good conductor of heat.
Answer : Mercury is a liquid which is a good conductor of heat. It is an exception, as all liquids are good insulator of heat.
Question 6: When you heat water in a pan, by which mode does most of the heat travel in water-conduction, convection or radiation?
Answer : When we heat water in a pan, the heat travels throughout the water through the process of convection.
Question 7: In which mode of transfer of heat does the medium not get heated up?
Answer : Radiation is a process in which the molecules don't transfer or carry heat from the hotter to colder regions, but the material itself radiates the heat energy. Therefore, it requires no medium to transfer the heat. Higher the temperature of the body, the more it radiates heat.
Question 8: A thermos flask consists of a double-walled glass vessel with the space between them filled with air, which is a bad conductor of heat. True of flase?
Answer : False. In a thermos flask, the space between the two glass walls is empty. This vacuum prevents heat loss through conduction and convection, as there is no medium present to transfer the heat by these two processes.
Question 9: Radiant heat falling on a body is partly absorbed and partly __________. Some of it may also be__________
Answer : Radiant heat falling on a body is partly absorbed and partly reflected. Some of it may also get transmitted.
