Learning Goal: To express temperatures using the Fahrenheit, Celsius, and Kelvin scales. Temperature is commonly measured in units of degrees Fahrenheit (F), degrees Celsius (C), or kelvins (K). The most familiar temperature scale in the United States is the Fahrenheit scale, in which water freezes at 32 F and water boils at 212 F. The scale often used by scientists is the Celsius scale, in which water freezes at 0 C and boils at 100 C. A third temperature scale, called the Kelvin scale, avoids negative temperatures by assigning 0 K to the coldest temperature possible, absolute zero. Use the following equations to convert between these temperature scales: (TF-32) 1.8 Part A TK Tc+273.15 where TF is the temperature in degrees Fahrenheit, To is the temperature in degrees Celsius, and TK is the temperature in kelvins. VE Convert 21.0 C to degrees Fahrenheit. Express your answer numerically in degrees Fahrenheit. View Available Hint(s) Submit Part B Tc = VE Submit ?
