Mechanical Engineering : Heat Transfer QUESTIONS AND ANSWERS :: part1 : 21 to 25

Following Mechanical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

21.Metals are good conductors of heat because

their atoms collide frequently
thier atoms-are relatively far apart
they contain free electrons
they have high density
all of the above.

22.Heat flows from one body to other when they have

different heat contents
different specific heat
different atomic structure
different temperatures
none of the above.

23.Pick up tne wrong case. Heat flowing from one side to other depends directly on

face area
time
thickness
temperature difference
thermal conductivity.

24.The insulation ability of an insulator with the presence of moisture would

increase
decrease
remain unaffected
may increase/decrease depending on temperature and thickness of insulation
none of the above.
