I have an Acer aspire laptop 5552 with windows 7 but it no longer works, i didn't get a reboot disc with it can you tell me how I can reboot it


if your warentee is up on your laptop, you would have to purchase a new o/s or a recovery desk from the windows website, or even buy a new laptop all together. Otherwise for warentee you are required to mail back the laptop with a copy of the reciept. I would also purchase tracking on your parcel just to make sure that you know it arrives.

What is the zip for leicester, wher postal code is le55pd


The postal code, or post code, is the UK's equivalent to the US system of zip codes.
If you put a house number and a post code on a parcel or letter, it will arrive just fine; post codes tend to cover under a maximum of about 75 houses.

How is latitude related to air temperature


The temperature of the troposphere generally decreases as altitude increases. The rate at which the temperature decreases, dT / dz, is called the lapse rate. The reason for this decrease is as follows. When a parcel of air rises, it expands, because the pressure is lower at higher altitudes. As the air parcel expands, it pushes on the air around it, doing work; but generally it does not gain heat in exchange from its environment, because its thermal conductivity is low (such a process is called adiabatic). Since the parcel does work and gains no heat, it loses energy, and so its temperature decreases. (The reverse, of course, will be true for a sinking parcel of air.) [1]
Since the heat exchanged dQ is related to the entropy change dS by dQ=T dS, the equation governing the temperature as a function of height for a thoroughly mixed atmosphere is

For dry air, which is approximately an ideal gas, we can proceed further. The adiabatic equation for an ideal gas is [3]

c4507116c9a4244af81e3aa8b865d863.png If the air contains water vapor, then cooling of the air can cause the water to condense, and the behavior is no longer that of an ideal gas. If the air is at the saturated vapor pressure, then the rate at which temperature drops with height is called the saturated adiabatic lapse rate. More generally, the actual rate at which the temperature drops with altitude is called the environmental lapse rate. In the troposphere, the average environmental lapse rate is a drop of about 6.5 °C for every 1 km (1000 meters) increase in height. [1]
The environmental lapse rate (the actual rate at which temperature drops with height, dT / dz) is not usually equal to the adiabatic lapse rate (or correspondingly, e52ae677de914e5cfddd35c399e2c57b.png). If the upper air is warmer than predicted by the adiabatic lapse rate (dS / dz > 0), then when a parcel of air rises and expands, it will arrive at the new height at a lower temperature than its surroundings. In this case, the air parcel is denser than its surroundings, so it sinks back to its original height, and the air is stable against being lifted. If, on the contrary, the upper air is cooler than predicted by the adiabatic lapse rate, then when the air parcel rises to its new height it will have a higher temperature and a lower density than its surroundings, and will continue to accelerate upward.[1][2]
Temperatures decrease at middle latitudes from an average of 15°C at sea level to about -55°C at the beginning of the tropopause. At the poles, the troposphere is thinner and the temperature only decreases to -45°C, while at the equator the temperature at the top of the troposphere can reach -75°C
