Question

thermal energy
is transferred by
conduction
whose transfer is
transferred by
which is used in all the
conventional heating systems including
in the form of
solar
and
electromagnetic
waves
and
hindered by
and

Explanation:

Thermal energy transfer methods include conduction, convection, and radiation. Convection is used in heating systems like solar, electric, and forced - air. Conductors help conduction, and insulators hinder it. Radiation is via electromagnetic waves.

Answer:

1. convection
2. radiation
3. conductors
4. insulators
5. electric
6. forced air
