How do Gas Fireplaces work to heat homes?
In additional to radiating heat into the room many gas fireplaces have a heat exchanger- cool air is drawn into the shell around the firebox, and warmed air comes out of the vents at the top.
How do convection uplift occurs?
A parcel of air is uplifted when it initially gains heat from the surface causing convective uplift.When the air is warmed by the surface it will expand and become less dense relative to air that surrounds it. - See more at: http://www.chacha.com/question/can-you-briefly-describe-how-convective-uplift-occurs#sthash.JinBHwPh.dpuf
Water from a natural hot spring is warmed by what inside the earth?
It is warmed by geothermal energy which is created by RADIOACTIVE DECAY http://en.wikipedia.org/wiki/Geothermal_(geology)
What is Convectional Precipitation?
Convectional rainfall occurs as a result of one of the three mechanisms that produce rain. When a fluid, such as air, is warmed from the bottom, for instance by earth warmed by sunlight, the lighter air rises drawing cooler air in underneath it. This sets up a so-called convectional flow. If the air near the ground is moist then when the it rises it will form clouds whose droplets coalesce to form convectional rain.
Which state of matter shows the largest change in volume when warmed or cooled?
The state of matter that shows the largest change in volume when warmed or cooled is gas. Liquids and solids increase and decrease in volume in response to temperature change as well, but not to the same magnitude as gases.
Where is inhaled air moistened and warmed?
Inhaled air is warmed and moistened in the nasopharynx and oropharynx.
How does air is warmed?
in the night
What does the air in the troposphere do when it is warmed by the land?
warms the air
Why is the air you breathe out warmer than the air you breathe in?
When you exhale, the air has been warmed by your body during the breathing process. As you breathe in air, it first enters your nasal cavity, where it is humidified and warmed to body temperature. This warmed air then moves to your lungs for gas exchange, and when you exhale, that warmth is transferred to the exhaled air.
What happens to the air at night?
what happens to air when it touches the warmed air
When air and atmosphere is warmed what does air pressure do?
When air is warmed, it expands and becomes less dense, causing it to rise. As it rises, it creates lower pressure at the surface. This is because there are fewer air molecules pressing down on a given area as the warmed air moves away.
When air in the atmosphere is warmed air pressure?
Warm front
What passages does the air get warmed and cleaned?
Air gets warmed and cleaned as it passes through the nasal cavity, where it is humidified, filtered, and warmed by the mucus and tiny hairs called cilia. Additionally, the air is further warmed and cleaned in the trachea and bronchi by the same mechanisms of mucus and cilia before reaching the lungs.
Where is air warmed and cooled in the human body?
in the esophagus.___.

What happens to air as it passes through the respiratory system?
air is filtered, warmed, and moistened.
Air from the outside is?
warmed, moistened and cleaned by the nose and mouth
