Why is kelvin used as measurement for temperature instead of degrees celsius?

Kelvin is an absolute scale, which makes much more sense once you understand that temperature is related to the speed of atoms (they can't have a negative speed). An absolute scale is one in which the lowest possible temperature is zero. An absolute scale also makes more sense in thermodynamics, where the ratios between two temperatures are often important.

Why can shell eggs be received at an air temperature of 45 degrees Fahrenheit or lower instead of an internal temperature of 41 degrees Fahrenheit or lower?
because of its hard shell
What is the value of sin22?
That depends on what angular measurement is used. Set your scientific calculator to the desired angular measurement (either degrees, or radians), then press 22, followed by sin. Or in more modern calculators, you press sin, followed by 22, instead.
Convert this -15 c temperature to the kelvin scale?
The conversion of Celsius to Kelvin: Kelvin = Celsius + 273.15. Instead of 273.15, the value of 273 is also used. so 273.15-15=258
Why do astronauts take measurement in centimeters instead of inches?

Why you use kelivin in calculation instead of celsius and Fahrenheit?
Kelvin has the advantage that it is an absolute temperature scale - it starts from absolute zero. This simplifies several calculations; for example, in an ideal gas, at constant pressure, the volume of the gas is proportional to the absolute temperature. Similarly, calculations related to heat machines are simpler if an absolute temperature scale is used.
Will the results be the same if you measured the temperature using degrees Fahrenheit instead of celsius are they equal?
No they are not equal.
SI unit of F?
The temperature in Fahrenheit is no SI unit. Use kelvin or degrees Celsius instead.
Metric units for measuring temperature?
Celsius or KelvinThe metric unit for temperature is the Kelvin (symbol: K), which is defined as 1/273.16 of the temperature difference between absolute zero and the triple point of water. The Kelvin (not degrees Kelvin) is mainly used in scientific fields.The degree Celsius (symbol: °C, formerly known as degrees centigrade) is of the same magnitude, but the zero is at 273.15 K. It is more commonly used than Kelvin for everyday usage, for example in weather forecasts and room temperature. It is not the official metric unit of temperature, but is accepted for use with the metric system due its close links with the Kelvin.Read more: What_is_the_metric_unit_for_temperature
What standard unit is used to measure temperature?
Usually it would be degrees Fahrenheit (°F).
Will spagetii cook faster with salt?
Yes, actually the salt makes your water boil at a higher temperature. So instead of your water boiling at 100 degrees Celsius it boils at 110 degrees Celsius. So when you put your noodles in they cook faster. :)
What does water freeze on the Celsius scale?
0 degrees Celsius, or 32 degrees Fahrenheit
What is a Metric Equivalent unit?
The metric system is not exactly equivalent to any other system, but there are units of measurement for anything that you may wish to measure. If you are accustomed to weighing things in pounds, you have the option of weighing them in kilograms instead. If you are accustomed to measuring length in feet, you have the option of measuring length in meters instead. You may be used to degrees Fahrenheit but you can use degrees Celsius instead.
What is Fahrenheit and Celsius based upon?
The celsius scale is a metric scale of temperature measurement. Unlike the Fahrenheit scale 0 degrees is freezing point and 100 degrees is the boiling point of water. The celsius scale is used anywhere the metric system is used. In addition to the Fahrenheit and celsius scale there is also the kelvin scale, used mainly only by scientists. Unlike other scales, on the kelvin scale 0 degrees is the lowest temperature possible (known as absolute zero and equivalent to -273 degrees in celsius) and there are therefore no negative readings.Early thermometers (like the one Galileo invented) did not have any scale (markings with numbers) to determine precise temperature.The 1st precise scale was developed by Anders Celsius in 1742. He used 'degree' as the unit of temperature. All of his standards for comparison to make his markings (on his scale) were based on the properties of water.Ø 100o was assigned the temperature at which ice melts at sea levelØ 0o was assigned the temperature at which liquid water boils at sea levelØ The region between (above and below, as well) these two extremes was separated into 100 equal units (degrees)In 1744, this was reversed to put the freezing point at 0C, and the boiling point at 100C. This is the scale in use today.Ø The two fixed temperatures that Celsius chose can be used to calibrate a thermometer (p. 195)
at what temperature does aluminium freeze?
Aluminum (or aluminium) doesn't solidify like liquids freezing into solids. Instead, it undergoes a phase change from a solid to a liquid when it reaches its melting point. Aluminum's melting point is around 660.32 degrees Celsius (1220.58 degrees Fahrenheit). This indicates that when exposed to temperatures above 660.32 degrees Celsius, solid aluminum transitions into a liquid state.
How can water be made to boil at 105 degrees Celsius instead of 100 degrees Celsius?
Water could be made to boil at 105 degrees C instead of 100 degrees C by adding a solute to the water. You can also raise the boiling point of water by moving to a higher elevation or putting it under higher pressure.
Does water boil at 95 degrees Celsius instead of 100 degrees Celsius in places like Denver Colorado?
The reason for this is that at higher altitudes, the atmospheric pressure is lower than at sea level. The boiling point of water is dependent on the pressure surrounding it. Remeber the equation PV=nRT. Here, P is for pressure and T is for temperature. Notice that as pressure decreases, so does the temperature. It is the same with the boiling point of water.
When did the weather bureau in AU begin to use Celsius instead of Fahrenheit?
The weather bureau in AU began to use Celsius instead of Fahrenheit temperature scale in 1960's just like the US.
