Sample Questions
Which of the following is a good thermal insulator?
Show answer
Thermocol
Thermocol has very low thermal conductivity (0.01 Wm⁻¹K⁻¹), making it an excellent thermal insulator.
Heat from the Sun reaches Earth mainly by:
Show answer
Radiation
Space is a vacuum, so conduction and convection cannot occur. Heat from the Sun travels as electromagnetic waves through space via radiation.
Which of the following substances absorbs heat radiation most efficiently?
Show answer
Black surface
Black surfaces absorb most of the incident radiation, while shiny or white surfaces reflect more.
The process of heat transfer in fluids occurs mainly by:
Show answer
Convection
In fluids (liquids and gases), heat is transferred by the actual movement of heated particles, known as convection currents.
