When matter is warmed does kinetic energy increase or decrease?
It increases. Heat is the kinetic energy of vibrating atoms/molecules.
Does air expand when its warmed?
yes it does.
Food being warmed by an infrared light is an example of heat transfer by?
Radiation.
What are two ways in which a person is warmed by the fire?
There are three ways in which heat is transferred, in general: conduction, convection, and radiation.Conduction doesn't apply in this situation (since a person isn't warmed by actually touch the fiery object), but the other two do.Radiation: A person is warmed by the heat radiating from the fire.Convection: The fire heats the air around it, which cycles through the room, heating the person nearby.
A 14.8g piece of metal is warmed so that its temperature increases by 7.58 degrees celsius.how much heat was transferred into it?
It depends on what the metal is. Different materials have different specific heats and will take various amount of energy to heat up. You need to find the specific heat of the metal used. Use Q=CmT Q=amount of energy C=specific heat m=mass T=change in temp
What causes the air in atmosphere to be unevenly warmed?
The suns energy
The Earth is warmed by solar energy. How is this energy transferred from the sun to the Earth?
By radiation: mainly in the infrared wavelengths.
When matter is warmed does kinetic energy increase or decrease?
It increases. Heat is the kinetic energy of vibrating atoms/molecules.
When the air in the atmosphere is unevenly warmed by the sun's what wind currents are the result'?
energy
Does ganymede have energy or sunlight?
Yes. Ganymede gets sunlight and is warmed on the inside by tidal energy from Jupiter and the other Galilean moons.
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)
How is the atmosphere near the earth's surface warmed?
Through conduction: the transfer of energy from matter touching another matter.
Solar houses without special equipment to collect sunlight?
A house without special solar equipment can still be warmed by the sun, which shines on walls, roofs and windows.
How has radioactive decay warmed the earth from the inside?
Radioactive decay of natural elements (Uranium is a big one) releases a large amount of energy, this energy heats up the earth. These elements are in the crust (underground) the mantly and the core. So the warmth they produce keeps the earth warm. Without this, the core would have cooled down and solidified by now.
What is the whole world warmed at?
The whole world is warmed by the sun.
How does being relaxed and easy going affect sport?
more energy but more able to stretch a muscle when you do the sport if not warmed up properly
Where is inhaled air moistened and warmed?
Inhaled air is warmed and moistened in the nasopharynx and oropharynx.
