WebThe specific heat, Cp, was determined by DSC on a series of resol-type phenol formaldehyde resins with varying phenol formaldehyde molar ratio. The extrapolated Cp values at 25°C vary between 1.181-1.206 kJ · kg −1 K −1 and the dCp/dT ratio was found to be 0.0042kJ · kg −1 K −2 in the temperature range of 70–125°C. WebIf specific heat is expressed per mole of atomsfor these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limitof 25 J⋅mol−1⋅K−1= 3 Rper mole of atoms (see the last column of this table). red carpet inn queens ny

The specific heat of water is 4.184 J/g °C (Table 12.3.1 ), so to heat 1 g of water by 1 °C requires 4.184 J. We note that since 4.184 J is required to heat 1 g of water by 1 °C, we will need 800 times as much to heat 800 g of water by 1 °C.
