1. It is known that the boiling point of water on the Kelvin temperature scale is 373.15 K and the freezing temperature of water is 273.15 K. A temperature scale, called the Reaumur (R) scale, is defined by identifying the freezing point of water as 0.0°R and the boiling point of water as 80.0°R. What is 62.3°R on the Kelvin scale? Clearly define your variables.

Perform the given calculation. You must round correctly and report the answer with the proper number of significant figures. 1.012×10−3 J/(0.012456 g)(298.3682−298.3567)K

Washington, D.C. has an average January temperature of 34.9 degrees Fahrenheit. What is this average if temp is expressed in Celsius? (Round to two decimal places.) [Hint: Conversion between Fahrenheit and Celsius is a linear transformation: Fahrenheit = Celsius*1.80 + 32, or Celsius = Fahrenheit*(1/1.80) - (32/1.80)]
