Heat rises, so unless your roof insulation is really crappy, the upstairs and attic will always be warmer.
Usually the top floor.
Heat rises, so on the top floor of a house, warm air from lower levels accumulates, making it warmer. Additionally, heat from the roof can radiate down into the top floor, further contributing to the higher temperature.
The house is warmer on top because heat rises.
Typically, the second floor is warmer than the first floor in a two-story home because heat rises. The warm air from the first floor tends to accumulate on the second floor, making it warmer. However, factors such as insulation, air circulation, and sunlight exposure can also impact the temperature difference between the two levels.
The top floor of a home is often warmer than the lowest floor because heat rises. As heat rises, it accumulates on the upper levels, making them warmer. In addition, the sun's rays may hit the top floor more directly, contributing to the higher temperature.
Warm air tends to rise, so all else being equal the second floor may be warmer than the first. This is complicated by forced air circulation, so in any particular house this may not be true, or at least may not be true all the time.
Heat rises, so the air near the ceiling tends to be warmer while the air near the floor is cooler. This is why you may feel cooler when closer to the floor. Additionally, the bed may trap heat from your body, making it feel warmer compared to the floor.
The reason that upstairs areas tend to be warmer is due to convection. Warm air rises, so unless there is some method of circulation, the upper floor (or the ceiling of a single level house) is where the warmer, less dense air will stay.
Your house can have a 'floor one' and a dungeon. If you consider the dungeon to be another floor, then yes. If not, then no.
Carpet provides better insulation than hard flooring, so it retains heat and feels warmer to the touch. The fibers in carpet trap air, which helps to insulate and keep heat close to the surface. This is why carpet feels warmer than the floor.
The East Room is on the second floor of the White House.
You can't. There is no to get a second floor added to your house.
