this is true. Singapore is near the epuater,thus the temperature never goes below 20 degrees
Of course they do! 20 degrees Fahrenheit is below freezing and Alaska does have a summer, no matter how short. They even go above 20 degrees Celsius in the summer and that is 68 degrees Fahrenheit.
The tundra.
it never goes below or above 70k
I like to keep my tank at 78 degrees, that seems to be the happy medium so if the power goes out(Cold) or on a very warm day in summer the temps will never go below 74 or above 82.
No because the latitude is 55 degrees N so the Sun never goes more than 11½ degrees below the northern horizon, so nautical twilight and astronomical twilight do not end.

Never reach 50 mph so the bomb never gets armed.
If it is 32 to 40 degrees F no problem, it's no different than your refrigerator but milk will freeze if it goes below 32 degrees F.
At the northern solstice the subsolar point reaches to 23.44° north, known as the Tropic of Cancer. Likewise at the southern solstice the same thing happens for latitude 23.44° south, known as the Tropic of Capricorn. The sub-solar point will cross every latitude between these two extremes exactly twice per year.
Of course as long as the winter never goes below 32 deg F
The thermostat is probably set for 190 degrees and that is the point it opens at.
At 25 degrees C the density of water is 1.0 g/mL. If the temperature of the water goes above 25 degrees C the density will drop. If the temperature of the water goes below 25 degrees C the density will rise.
