This question requires a subjective answer, but I say that 51.5 F is neither.
72 F is a pleasant room temperature, neither hot nor cold.
Well 30 C is hot, 30 F is cold. That depends if it is 30 degrees Celsius or 30 degrees Fahrenheit. If it was 30 degrees C then it would be hot because it is around 85 degrees F. If it was 30 degrees F....then it would be darn cold.
32º Celsius is very warm. It equates to 89.6º Fahrenheit.
Not hot at all - it is extremely cold: -457.87 F
Hot and cold are not quantified terms, only comparative terms (hotter than or colder than). The temperature scale runs from absolute zero (minus 459.67 degrees Fahrenheit) to several billion degrees. With this kind of range most of the temperature we experience are "cold" in terms of the Universe. For our normal experience ranging from -40 degrees F in the air outside of a jet aircraft to several thousand degrees in the engine of the same aircraft 0 F is still on the lower (cooler) end of the scale.However if the comparison is the temperature that you have to keep most gases liquid, 0 F is far too hot.
72 F is a pleasant room temperature, neither hot nor cold.
Hot and cold are comparative terms. 36 degrees F is considerably colder than 36 degrees C
Well 30 C is hot, 30 F is cold. That depends if it is 30 degrees Celsius or 30 degrees Fahrenheit. If it was 30 degrees C then it would be hot because it is around 85 degrees F. If it was 30 degrees F....then it would be darn cold.
For a human being, cold. For a domestic food freezer, just about right.
In the weld area the steel is molten 2800 degrees F +. The arc can reach 5000 degrees F +. Surrounding areas anywhere from cold to 2800 degrees F.
Temperatures can plunge to below -120 degrees F in the Antarctic Desert or be as warm as +134 degrees F in the Mojave Desert.
Jupiter is not really hot then you think it is =]!! Actually, the surface of Jupiter is VERY cold about -250 degrees. But the core is about 5000 degrees (f)
Temperature measures how hot or cold something is in degrees Celsius (°C) or Fahrenheit (°F). It is a scalar quantity that can be measured using thermometers or other temperature sensors.
32º Celsius is very warm. It equates to 89.6º Fahrenheit.
Normal body temperature for humans is about 37 degrees C or 98.6 degrees F.
Temperature is recorded in degrees Celsius (°C) or degrees Fahrenheit (°F). It is a measure of how hot or cold an object or environment is.
i think its hot and cold but most of it its bot
