Important Questions on Heat in Everyday Life
Central air conditioning systems
Central air conditioners circulate cool air through a network of supply and return pipes. These ducts carry cool air from the air conditioner to the home. This cooled air becomes warmer as it circulates through the home; then it flows back to the central air conditioner through return ducts. A typical central air conditioning system is a split system, with an outdoor air conditioning, or “compressor bearing unit” and an indoor coil, which is usually installed on top of the furnace in the home. Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home. Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby “cooling” the air. The heat that has transferred to the coil is then “pumped” to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.

How are the heat and moisture removed from home?
(Choose from radiation waves, conduction vibrations or convection currents).
A utensil, which is made of thick copper base, is placed on the gas burner to heat up water in it.
Explain why water would boil faster when a lid is placed on the utensil.
