What is thermodynamic temperature scale?
The thermodynamic temperature scales are based on the third law of thermodynamics:The entropy of a system approaches a constant value as the temperature approaches zero. The entropy of a system at absolute zero is typically zero, and in all cases is determined only by the number of different ground states it has.The two commonly used thermodynamic temperature scales are Kelvin (K), which has temperature increments the same size as Celsius and Rankine (°R), which had temperature increments the same size as Fahrenheit.The thermodynamic temperature scales are further defined by extrapolation of the values PV at given temperatures as pressure approaches zero and thus the ideal gas law becomes a better and better approximation.
The ideal gas equation will only give correct values if the temperature is expressed in degrees?
The ideal gas equation will only give correct values if the temperature is expressed in degrees Kelvin.
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.
What is it called when two values change in opposite directions?
The values are said to have negative correlation.Values that change regularly at matching rates are said to be inversely proportional.
What describes something that is quantized?
It has a specific set of possible values
Which temperature scales has no negative temperatures?
The Kelvin scale has no negative values because 0 K is absolute zero, no motion.
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.
Why are there negative numbers?
Because there are negative values as for example the temperature can be -12 Centigrade
What is the Fahrenheit temperature for -40 Celsius?
It is -40 deg F. This is the only temperature when the numerical values on the two scales are the same.
What is the definition of negative numbers?
A negative number is any real number that is less than zero. Such numbers are often used to represent the amount of a loss or absence. For example, a debt that is owed may be thought of as a negative asset, or a decrease in some quantity may be thought of as a negative increase. Negative numbers are also used to describe values on a scale that goes below zero, such as the Celsius and Fahrenheit scales for temperature.
What are not a possible value for a probability?
Negative values, values greater than 1, complex values.
What temperature is hotter 31 degrees fahrenheit or 29 degrees fahrenheit?
31 degrees Fahrenheit is hotter. All modern temperature scales represent warmer temperatures by higher positive degree values.
What possible values can the growth factor have in an exponential decay equation?
Any number below negative one.
What is the significance of negative values of voltage and current?
What is the significance of negative values of voltage and current?Negative values show direction and that is the significance
Are Fahrenheit and celsius the same?
No. They are two separate scales, and the values are completely different.SimilaritiesBoth scales measure temperature and both use the freezing and boiling points of water to define values. Both use intervals called "degrees".DifferencesThe sizes of the intervals (degrees) are different. A degree Celsius is 1.8 times as large as a degree Fahrenheit, which is why common temperatures expressed in Fahrenheit have larger numerical values. (e.g. 30°C = 86°F)The 0° point for Celsius is at the freezing point of water. That same temperature (water freezes into ice) is at the 32° value on the Fahrenheit scale.The commonly used values :0°C = 32°F = water freezes100°C = 212°F = water boilsTo convert between scales :Fahrenheit temperature = (9/5 x Celsius temperature)+ 32Celsius temperature = 5/9 x (Fahrenheit temperature - 32)
Why do negative numbers exist?
Negative numbers exisit because negative numbers are useful to describe values on a scale below zero (0), such as temperature and also book kepping where they can be used to represent credits
If the possible values of a random variable X are between -1 and 6 is the mean of X positive or negative?
It could be either.
