In winter if the temperature of surroundings go down by 5 degrees you will feel cold
Nothing much will happen.
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 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, thenv = 331.5 + .6*-5 = 328.5 m/sThere 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.
The beaker will eventually cool down, while the room will warm up. The room, having a much larger mass, will only warm up slightly.
It is absolute zero and all molecular motion stops
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.
It would get too cold for the human body. You would die! The temperature would be -400 degrees Celsius!
