Answer to Question 1

D

Answer to Question 2

Temperature is a measurement of the average kinetic energy of molecules in matter. Heat is the flow of kinetic energy between molecules. The three primary temperature scales are Fahrenheit, Celsius, and Kelvin. Fahrenheit places the melting point at 32 and the boiling point at 212. Celsius is divided into 100 degrees using a decimal system, with a melting point at 0 and a boiling point at 100. The Kelvin scale starts with an absolute zero, with temperature readings proportional to the actual kinetic energy. Melting point for ice is 273 and boiling point for water is 373.
