The speed of sound is given by the formula v = 331.5 + .6T, where T is the temperature of the air in degrees Celsius. If T were negative, then you would simply have a speed of sound less than 331.5 m/s. For example, if T = -5 degrees Celsius, then
v = 331.5 + .6*-5 = 328.5 m/s
There really isn't anything magic about an air temperature of 0 degrees Celsius. Zero degrees Celsius is the temperature at which water freezes, but nothing particularly interesting happens to _air_ at that temperature.
Change Of Temperature. For Example; Water Freezes At Zero Degrees Celsius. Frozen Water (Ice) Melts Into Water (Usually) At Twenty Degrees Celsius; Try Holding It In Your Hands Or Mouth For About Five Minutes. Water Can Then Evaporate At Higher Temperatures Into Steam (Which Is Usually On Windows And Mirrors After You Get Out Of A Shower.

If nothing else changes, the relative humidity will fall.
It will sink
It wouldn't t be able to cool down below 32 degrees without freezing first. As heat is take away from the substance, it would first cool down to 32 degrees (assuming it was hotter than that in the first place), then, as more heat is taken away, it would solidify, and only after getting solid will it continue getting colder.
It is absolute zero and all molecular motion stops
Nothing much will happen.
In winter if the temperature of surroundings go down by 5 degrees you will feel cold
It will gradually drop to below 10 degrees.
when the temperature gets below 32 degrees Fahrenheit (0 degrees celsius), water freezes
nothing
A temperature of 9 degrees Fahrenheit does not equal 5 degrees Celsius but a change of 9 degrees Fahrenheit equals 5 degrees Celsius. This happen because neither is an absolute scale.
Heat will flow from the warmer to the cooler body. The object at 70º will cool down and the object at 50º will warm up.
The water would have evaporated long before the temperature reached 374 degrees.
The beaker will eventually cool down, while the room will warm up. The room, having a much larger mass, will only warm up slightly.
At 30 0F this liquid become a solid (this is water).
I must assume that you are referring to 29.5 degrees Celsius. Normal human body temperatureis 37.0 degrees Celsius. The abbreviation for Celsius is C , such as 37.0 C. The temperature youhave given, 29.5 C , is far below the normal human body temperature.
