- Convert 36 kcal to J Record the answer in scientific notation (e.g. 2.10E3J)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)K1. 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.
