How is heat transferred by convection out of a house?
Air inside the house next to a heat source is heated. The warmer air is less dense than colder air so it rises and moves around in currents. The warmed air may escape through gaps in doors or open windows, or it may transfer it's heat to a wall, which may allow heat to then escape through the wall by conduction.
Why do woolen clothes keep warm?
Because the wool fibers are good at trapping air and air traps heat.in winter it traps the heat and does not allow it to escape and thats how the wollen clothes keep us warm in winter
How do you deflate a balloon by using a lighter?
The heat from the lighter, when placed on the surface of the stretched surface of the balloon,would melt the plastic of the balloon and allow the air inside the balloon to escape, so deflating the balloon.
Why are foam and fiber glass good heat insulators?
i think it is due to them having air spaces so it takes longer for heat to escape
What physical properties allow hot air balloons to fly?
Heat, the heat from the flames below the balloon cause the balloon to rise.
Do the lungs clean dirty blood?
The lungs do not clean dirty blood, although they do allow excess carbon dioxide to escape into the air. Dirty blood is filtered by the kidneys, not the lungs.

Does air temperature allow air to escape balloons faster?
Yes
What will happen if you don't insulate?
You will be cold in the winter and hot in the summer. If you heat your house, all the heat will escape. If you use an air conditioner, all the cold air will escape.
Why Air-conditioner become less efficient when it is dirty?
It can't transfer heat as efficiently when the exchanger is dirty.
What is the word which means to let the air out of a balloon or tire?
Deflate is to allow air to escape from a balloon.
What causes the heat pump high pressure limit to trip?
Dirty Air Filters or dirty coil on inside unit.

Will a new cabin filter help your heat on a 2000 dodge Dakota?
It might, but not guaranteed. If there is a cabin air filter to begin with, and the old filter is very dirty, a new one will likely allow better airflow.
