In science, the most common temperature scale is the Celcius or Centigrade scale. Thus there are 100 Celcius degrees between the freezing and boiling of water. A third temperature scale is the Kelvin scale, which we'll use much more later. In the Kelvin scale, water freezes at 273.15 K, and 0 K is the coldest temperature that can exist. The size of the Kelvin degree is the same as the Celcius degree.
Heat is a form of energy, and is most commonly measured in calories or joules .
C to 15.5 o C. A calorie is 4.184 joules. Where m is the mass of the substance, D T is the change in temperature, and C s is the specific heat of the substance. The specific heat is an intensive property of a substance. Most metals have smaller specific heats. The periodic table is a source of information you will always have at your disposal.
