What is the definition of temprature?
Temperature is measure of hotness or coldness of an object .
What is a good definition of temperature?
the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
How energy is related to heat and temperature?
Heats a measure of energy. Temperature is a measure of hotness
If today's maximum temperature was 14 degrees celsius and tomorrow's maximum is expected to be 28 degrees celsius will tomorrow be twice as hot as today?
Zero degrees Celsius (or centigrade) is the same as 32 degrees Fahrenheit. Therefore, if you convert the temperature to Fahrenheit, and we are working on a twice (as cold) minus reduction, then tomorrow could be 16 degrees Fahrenheit?it doesn't ask for Fahrenheit. if it is 0 now and twice as cold tomorrow, 0 x 2 = 0. it will be 0 degrees Celsius.If we use the Kelvin scale 0'C = 273.15'K so twice as cold would be 546.3' K or 273.15' C not a realistic answer for Earthly temperatures.Another Answer"Double the coldness" is meaningless. "Cold" is merely a lack of heat. Temperature is a measure of heat, not cold. Moreover, even if you could measure "coldness", you would have to use some unit of measurement that starts at zero when there is no coldness, and increases as it gets colder (the opposite of temperature). I'm not talking about Kelvin, because the zero on the Kelvin scale is set where there is no heat, not where there is no coldness. Presumably, the point of "zero coldness" would be the point at which the highest possible temperature is obtained, and therefore there is no coldness at all. But theoretically, there is no maximum temperature, and therefore no point of "zero coldness". But, even if you could establish what the maximum possible temperature (and therefore the zero point on your "coldness" scale) was, it would be so high that doubling coldness would result in a temperature of less than absolute zero, which is impossible. For example, even if the maximum possible temperature was as low as 600 degrees F (and we know that the average star burns many, many times hotter than that), 600 degrees F is approximately 316 degrees C, or 589 K. If you set your "zero coldness" at this point, 589 K, and increased your coldness measure by 1 for every 1 degree decrease in K, your coldness measurement would reach 316 at 0 degrees C. If you double this, you have a coldness measurement of 632, which equates to a Kelvin temperature of -43. But negative Kelvin temperatures do not exist. QED - there is no such thing as "twice as cold".
When does heat stop moving?
Heat flows from a high to a low. Therefore, heat stops moving when there is no gradient. This fact forms the basis of an accurate technique used to measure the properties of a thermal insulator. Instead of trying to measure the heat flowing through a sample, It is sufficient to measure how much heat energy is added to one of the faces to minimise the heat flow. For it is easier to measure when a flow approaches zero, than to measure its actual value. This is known as the 'Guarded Hot Plate Method'.
How does meteorologist measure he hotness and coldness of the air?
They use "thermometers", and they report the hotness and coldness in terms of "temperature" units.
