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.
Water vapours that condenses on a surface having temperature below 0 0C are converted into ice which is often known frost.
Both temperature and pressure increase as depth increases.
Increase
It depends on the pressure of the system that the water is in. In atmospheric pressure (ie at sea level and in the open) water turns into steam at 100 degrees Celsius. At higher pressures this temperature decreases.
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
Not enough data is supplied to answer this question. Some substances are more reactive to colder temperatures; however, in most cases, the higher temperature would increase the rate of reaction.
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.
