A central gas fired, forced hot water heating system with room baseboard units provides most of its heat transfer in which one of the following ways?
(1) convection
(2) combustion
(3) collection
(4) radiation

Joists are:
(1) beams that support walls and floors.
(2) beams that support the foundation.
(3) beams that support floors and ceilings.
(4) beams that support the foundation and ceilings.

A 200 watt light bulb operating at 120 volts requires a current of:
(1) 2.2 amps.
(2) 200 amps.
(3) 0.83 amps.
(4) 1.67 amps.
4
An advantage of using a central, gas-fired, forced hot water heating system is:
(1) its air filtration capabilities.
(2) the production of a steady, consistent heat.
(3) that money can be saved by leaving it off during an owner’s winter absence.
(4) that heat transmission is completely by radiation.
