As temperature decreases with height it gets colder in the mountains . But this phenomenon is negated as 3rd floor is warmer than ground floor(especially during the summer).

As you go up in altitude, the air does get cooler since it's less dense, and can therefore retain less heat. However, this heat loss is 2 degrees Celcius per 1000 feet. So, for the height of a three story house, at about 35 feet, the cooling effect would be .07 of a degree. Hardly enough to notice. You have to go much higher than your house to notice any cooling effect. The air near the surface is constantly in motion, and you can't measure differences over such a short scale.
Anyway, as others have stated, hot air rises, and unless you have a large vent on your top floor, it will collect there and heat the upper floors.

Bah Humbug! Yes, Heat Does rise. Yes, it gets cooler in the mountains.
The heat we get in the summer rises. Eventually, the air cools off. The cooler air in the atmosphere cools it down. This is why the mountains are cool. But, In the Troposphere, the air gets warmer. And the higher you get in the troposhpere, the hotter it gets.
Anyway, the reason why the higher floors get warmer, is because you are enclosed in a building. The warm air eventually accumulates at the top of the structure. If there is a basement, the ground around the basement is cooler than the air above. So, the cool ground helps cool of the basement. So, you will feel even a bigger temperature difference.
Of course, Many commercial buildings have an AC for every floor. So, there you can't really feel the difference.

This is because of the effective green house effect which is more substantial near earth's crust. As u go above the intensity of reflected rays goes on decreasing coz of ur upper floor have adopted some of them, resulting in their temperature increase whereas ur lower floors are not exposed to the reflected radiations. So this phenomenon of decreasing the temp with height comes into play after a particular height only.
Adding ur top floors recieive direct rays from sun but not the ground ones.

"The higher you go the colder you feel". The temperature decreases with the altitude because of the decreament of atmospheric pressure. Mind it in air there is no roof, no ceiling no building! Why are you trying to lift our buildings to sky high. Lower floors get colder during night and during day sun's heat gradually penetrates floors starting from the top floor , because offcourse, it is on the first in the queue.Once again you did not say which floor do you live!!!

The roof of the house get direct sun rays and thus heating the top floor,where as the ground floor or the basement is comparatively cooler as it is not receiving direct sun rays or we can say that there are other floors above it.In the case of mountain as the altitude increases from the sea level the temperature decreases.

The top floor of the house is hotter than the ground floor because it is exposed to direct sunlight wheras the ground floor of the house is not. We assume the normal condition when the top floor is covered by a roof. When the roof is exposed to direct sunlight, the bricks get heated up. As a result the rooms in the top floor experience more heat. the ground floor remains cool because the air in the rooms at the top floor does not allow the heat to travel to the ground floor as air is a ad conductor of heat.

Cold air sinks while heat rises. Cold air is more dense thus it falls to the lower part of the house. As more cold air fills the basement or ground floor the heat rises to the top of the house. This is why attics are so hot and why we put ventilation on our roofs. Of course when you think about mountainous regions being colder which you would think voids our theory, but the atmosphere is very thin which allows the cold air to flow freely upward. When this air mixes with the warm climate moving northward in our Midwestern states, we develop thunderstorms and tornadoes.

Yes, as one increases in altitude, the temperature generally gets cooler, but in a small, confined loction such as a house, you are confronted with the fact that warm air rises. Sunlight strikes the home, and causes the air inside to heat up. Naturally, the warm air wants to rise above the cooler air in the house. This means that the warmer air accumulates in the top floors of a house, unless sufficient ventilation exists to expell the warmer air, and draw cooler air into the house. That's why the ground floor/basement of a home tends to be cooler in the summertime.

yes temperature decreases with height but in this case the roof is made up of such a material that it absorbs heat very quickly and releases very slowly . the ground floor does not get much heat as compared to top floor but if there is middle floor it might b cooler as ground floor part also gets some heat from earth

Look,it is a prove fact that temperature decreases with height but it is really simple that in summers the upper floor is warmer than the lower floor simply because as we come closer and closer with the sun,we tend to feel the heat coming from sun rays more and more.So,when we are on a upper floor we feel More heated as compared to when we are on a lower floor.
