The time it takes for a lake to freeze at minus one degree Celsius for eight hours depends on several factors, including the depth of the water, wind conditions, and the presence of ice already formed. Generally, shallow lakes freeze faster than deeper ones, and still air allows for better ice formation. While a thin layer of ice might start to form in eight hours, it usually takes significantly longer for a lake to freeze solid enough for safe activities. Therefore, while some surface freezing may occur, a complete freeze is unlikely within that timeframe.
That is eight hours.
Eight hours.
-40
6 hours 24 minutes.
-15ºC = 5.0ºF
It is minus one half.
Sixty eight minus thirty eight equals thirty
The term "a number minus eight" can be symbolized as x - 8.
25 degrees centigrade equal 77 degrees Fahrenheit.
Eight minus one and one ninth equals six and eight ninths.
Water freezes at 0 degrees Celsius (32 degrees Fahrenheit), so at minus 11 degrees Celsius (12.2 degrees Fahrenheit), it would freeze relatively quickly. The exact time it takes for water to freeze can vary based on factors like the volume of water, container shape, and air circulation. Generally, smaller volumes of water freeze faster than larger ones. In cold conditions, like minus 11 degrees, freezing can occur within minutes to a couple of hours.
Eight minus two thirds would be seven and one third.
