  2. Vapour pressure of water - Wikipedia

    en.wikipedia.org/wiki/Vapour_pressure_of_water

    The analysis here shows the simple unattributed formula and the Antoine equation are reasonably accurate at 100 °C, but quite poor for lower temperatures above freezing. Tetens is much more accurate over the range from 0 to 50 °C and very competitive at 75 °C, but Antoine's is superior at 75 °C and above.

  4. British thermal unit - Wikipedia

    en.wikipedia.org/wiki/British_thermal_unit

    It is the rate of heat transfer needed to freeze 1 short ton (907 kg) of water into ice in 24 hours. In the United States and Canada, the R-value that describes the performance of thermal insulation is typically quoted in square foot degree Fahrenheit hours per British thermal unit (ft 2 ⋅°F⋅h/Btu). For one square foot of the insulation ...

  7. List of cities by average temperature - Wikipedia

    en.wikipedia.org/wiki/List_of_cities_by_average...

    This is a list of cities by average temperature (monthly and yearly). The temperatures listed are averages of the daily highs and lows. Thus, the actual daytime temperature in a given month may be considerably higher than the temperature listed here, depending on how large the difference between daily highs and lows is.

    Cyprus from Space Solar Map of the Island Mountainous Geography on the northern coast Seacoast from Southern Side Sunsets on the island Seacoast from Eastern side. Cyprus has a subtropical climate, Mediterranean and semi-arid type (Csa and BSh) according to Köppen climate classification, [1] [2] with very mild winters on sea level and warm to hot summers.

  9. Climate of the United Kingdom - Wikipedia

    en.wikipedia.org/wiki/Climate_of_the_United_Kingdom

    Rare summer heatwaves of 28 °C+ occur on occasion, but sustained is uncommon, due to the high latitude and cool martime climate. London is vulnerable to climate change in the United Kingdom, and there is increasing concern among hydrological experts that London households may run out of water before 2050. [4]
