Answer:
Step-by-step explanation:
Three temperature scales are currently in use. Their units are °F (degrees Fahrenheit), °C (degrees Celsius), and K (kelvin). The Fahrenheit scale, which is the most commonly used scale in the United States outside the laboratory, defines the normal freezing and boiling points of water to be exactly 32°F and 212°F, respectively.
The Celsius scale divides the range between the freezing point (0°C) and boiling point (100°C) of water into 100 degrees. The kelvin is the SI base unit of temperature: it is the absolute temperature scale. By absolute we mean that the zero on the Kelvin scale, denoted by 0 K, is the lowest temperature that can be attained theoretically. On the other hand, 0°F and 0°C are based on the behavior of an arbitrarily chosen substance, water.
The size of a degree on the Fahrenheit scale is only 100/180, or 5/9, of a degree on the Celsius scale. To convert degrees Fahrenheit to degrees Celsius, we write:
?ºC = (ºF - 32ºF) * 5ºC/9ºF
The following equation is used to convert degrees Celsius to degrees Fahrenheit:
?ºF = 9ºF/5ºC * (ºC) + 32 ºF
Both the Celsius and the Kelvin scales have units of equal magnitude; that is, one degree Celsius is equivalent to one kelvin. Experimental studies have shown that absolute zero on the Kelvin scale is equivalent to –273.15°C on the Celsius scale.
Thus, we can use the following equation to convert degrees Celsius to kelvin:
?K = (ºC +273.15ºC) * 1K/1ºC
