Thermal conductivity and specific heat were measured for a Group II conventional mineral oil-based diesel engine lubricant and a Group V-based LHR diesel engine lubricant. As we said, heat is a form of thermal energy. 8°F (1°C) at normal air pressure. 18 J/g∙C 3. Derived quantities that specify heat capacity as an intensive property, i. Specific Heat Worksheet Name (in ink): C = q/mAT, where q = heat energy, m = mass, and T = temperature Remember, AT = (Tfinal — Tinitial). 140 J/g°C. Addison January 22, 2001 Introduction In this section we will explore the relationships between heat capacities and speciﬂc heats and internal energy and enthalpy. The heat capacity, or 'thermal mass' of an object, is defined as the Energy in Joules required to raise the temperature of a given object by 1º C. 0 g of water: a) (40
