A car parked in an open ground gets much hotter than the surrounding air. But heat flows from hot to cold zone

You misunderstand the process going on.  The car isn't absorbing convective heat from the surrounding air.  It's absorbing radiant heat from the sun.  It gets so hot because the closed car acts as a greenhouse containing the heat.  Also, a close car is pretty well insulated so it can't lose the heat very well through convection.

Not 100% sure. But I think its because the air inside isn't moving. The air inside is stationary, while it is continuously circulating outside, which causes changes in the temperature. IMHO

It's tranferred to heat/friction from the impact

If the coolant level is dropping, it is going somewhere.  If you can't find any leaks or see coolant on the ground then it's probably the head gasket.

when the windows are rolled up the air in the car isn't moving as fast as the air outside the car. the air is moving as it would if the car were perfectly still almost

The black paint gets hotter in the sun, more than lighter colored cars,due to radiant heat. the birds can pick up this temprature differance with thier eyes and will drop there or near the car.

It's not cold enough.

its heat; radiators give off heat and so does the friction caused by moving atoms

Friction, Heat generated to name 2 reasons.

Sleet. Hail is different, it's accreted.

Heat flows through three mechanisms:\n\n(1) Conduction --- This is what happens when you hold a piece of metal with the other end in a flame. The heat is conducted to your fingertips.\n\n(2) Convection --- This is what happens when you turn the furnace on in the morning. The warm air coming from the outlet mixes with the rest of the air in the room and you feel the heat.\n\n(3) Radiation --- This happens when you step out into the sunlight or under a heat lamp. The radiated heat is the same thing as visible light. It is just a longer wavelength. \n\nThe earth receives radiation from the sun. There is also a small amount of heat carried up from the core where nuclear fission still takes place. This is conducted by both convection (magma) and conduction. There is also a minute amount of heat from fires etc. But most of earth's heat comes from the sun.\n\nThe earth surface loses some heat to the atmosphere (you should be able to figure out which of the three is taking place here). But the biggest loss is radiating heat out into space. The greater heat flow will be from the warmer object to the cooler object. Since space is only a few degrees above absolute zero (search for: "absolute zero" kelvin) the earth loses heat to space.\n\nYou can easily see this on a cool night. Your car will conduct heat to anything contacting it. Heat from the inner parts of the car will conduct to the outer skin of the car. There it will warm the air slightly. The air will carry the heat off through convection. This will continue until the car and the air are the same temperature.\n\nBut, the car is also exposed to space and will continue to radiate heat to space, even after it is colder than the surrounding air. As a result, dew will start to form on the cold car surfaces. If the car is parked under a car, it is not exposed to space. It will not radiate heat off into space. It will still radiate heat, but it will also receive heat back from the tree, which is also radiating. So the car will not cool down far enough to form dew.\n\nIf you are interested in space in general and the moon in particular, try:\nhttp://groups.yahoo.com/group/lunar-observing/\n\nClear Skies\n\nChuck Taylor

The hotter the surface gets the more resistance. It is a solid state item.

When heat radiates off the earth it causes the air right above the ground to heat up and then refract ( bend ) light so that light coming from the sky gets sent to our eyes like it was coming off the ground.  Drive down a highway in the summer.  Look off in the distance and it will appear that there is water on the ground.  This phenomenom (sp?) also happens in the dessert and can trick one into believing water is just a few hundred yards away.
