Why does the ice in an ice skating rink never melt?
Ice skating rinks use a special type of ice called "hard ice" which is different from the ice that forms on a lake or river. Hard ice is made by freezing water in a controlled environment, which removes impurities and creates a smooth, durable surface. This ice is also much denser than natural ice, which makes it more difficult to melt.
In addition to the special type of ice, ice skating rinks also use a refrigeration system to keep the ice from melting. This system circulates cold air through pipes under the ice, which chills the ice and prevents it from warming up. The refrigeration system also helps to remove any moisture from the air, which further helps to keep the ice from melting.
As a result of these factors, the ice in an ice skating rink is able to stay frozen even in relatively warm temperatures. This allows skaters to enjoy their sport without having to worry about the ice melting.
