Why is Kelvin scale adopted for chemical calculations?
There are two types of numerical scales available: relative and absolute. A relative scale arbitrarily (i.e. as judged by the person) assigns a point of origin that is said to be equal to "zero". While in some cases this makes measurement for some values quite simple (e.g. the freezing point of pure water is 0 Celsius), in other cases moving to the left of the zero mark (that is, producing negative values) could cause formulas to produce unintended results. On the other hand, an absolute scale relates the origin to some absolute and definite zero. In the case of the Kelvin, the "zero" chosen corresponds to the temperature where the kinetic energy of a perfect crystal of matter is equal to zero. For one thing, this resolves the difficulty of determining what "zero" actually stands for. Another advantage of the Kelvin scale is that it is incremented in absolute values, that is, all values are always positive. This eliminates the problem of factoring in negative values into a particular equation. Answer When doing chemistry, it is always a good idea to use Celsius or Kelvin, simply because it is measure of temperature that is understood in the majority of the world. Kelvin is simply more accurate to the hypothetical "absolute zero" than Celsius.
Each degree on the Kelvin scale equals?
The relationship between Kelvin and Celsius scale is K=C+273. 15. Where K is Kelvin temperature and C is Celsius temperature. Each degree on the Kelvin scale equals the same degree in Celsius scale differing only in the zero value. The freezing point of water and absolute zero are the zero values of Celsius and Kelvin scale respectively.
The ideal gas equation will only give correct values if the temperature is expressed in Kelvins true or false?
False. Kelvin is the same as celcius, except that absolute zero is −273.16°C whereas it's set to zero °K.
Why was kelvin scale was made?
The Kelvin temperature scale (K) was developed by Lord Kelvin in the mid 1800s. The zero point of this scale is equivalent to -273.16 °C on the Celsius scale. This zero point is considered the lowest possible temperature of anything in the universe. Therefore, the Kelvin scale is also known as the "absolute temperature scale". At the freezing point of water, the temperature of the Kelvin scale reads 273 K. At the boiling point of water, it reads 373 K. Whereas the Kelvin scale is widely used by scientists, the Celsius or Fahrenheit scales are used in daily life. These two scales are easier to understand than the large numbers of the Kelvin scale. Could you imagine waking up to your radio and hearing the DJ give a weather report like this: "It's going to be a beautiful day today with sunny skies and a balmy temperature of 297 K!" That's 24 °C or 75 °F.
Why do scientists favor the kelvin scale?
The zero in the Kelvin scale is the absolute zero in the universe. Physical equations are usually referenced to 0 K, the zero-energy point. It is easier to do scientific calculations using the Kelvin than the Centigrade (0 K = -273 C) or Fahrenheit (0 K = -460 F). Imagine you have a ratio (T1/T2) in the expression. Using the Centigrade values for T1 and T2 will give the wrong answer.
Which temperature scales has no negative temperatures?
The Kelvin scale has no negative values because 0 K is absolute zero, no motion.
What is the mathematical equation used to convert temperatures between the Kelvin temperature values and degrees Celsius and visa verse?
Temp in Kelvin = Temp in Celsius + 273.15° Have a look at Absolute Zero on Wikipedia.
Which scale of temperatures does not have negative values?
Kelvin scale
What is the SI unit of temperature?
The unit is the Kelvin. Zero on the Kelvin scale is the coldest possible temperature, absolute zero. The scale increases by the same degree intervals as the Celsius scale but since Kelvin starts at absolute zero, the values are all higher. For example, it is 273.15 K when it is 0°C (Celsius). Kelvin "K" It is KELVIN!!!!! Either Kelvin, or Celsius. Both are used with the SI K degreeskelvin
In applying Charles' law temperature must be in what scale?
The "Kelvin" scale, which uses the same size of degree as Celsius, but with a zero value at absolute zero. (on the Celsius scale, absolute zero is -273.15° C) There are no negative temperature values on the Kelvin scale.

What is the product of 3 integers with the same sign?
It is the product of their absolute values with the common sign.
What temperature scale does not use degree?
The temperature scale that has no negative values is the Kelvin scale, because it has its zero point at the lowest possible measurable temperature (absolute zero).The similarly based scale using Fahrenheit intervals (degrees) is the Rankine scale. The Kelvin scale starts at (the minimum) absolute zero. (0 K = -273 oC)
Each degree on the Kelvin scale equals?
The relationship between Kelvin and Celsius scale is K=C+273. 15. Where K is Kelvin temperature and C is Celsius temperature. Each degree on the Kelvin scale equals the same degree in Celsius scale differing only in the zero value. The freezing point of water and absolute zero are the zero values of Celsius and Kelvin scale respectively.
When adding integers with the same sign do you add their absolute values and write the common sign?
yes.
Why celsius scale gives negative temperature?
Temperature in Celsius can be negative. 0 degrees is freezing point in Celsius, so it is possible to get -1, -10 degrees, etc. However, not all temperatures in Celsius are negative.
Protein catalysts which cause reactions to occur at temperatures and pH values common to living cells are?
Enzymes
