Youwill also encounter the term specific heat, the heat required to raise one (1) gram of a material one (1) degree Celsius. One calorie of heat is equivalent to 4.187 J. Typically, we use the SI units of Joules (J) andkilojoules (kJ). Heat energy is measured in kilocalories, or 1000 calories. Work and heat can both be described using the same unit of measure.Sometimes the calorie is the unit of measure, and refers to the amountof heat required to raise one (1) gram of water one (1) degree Celsius. Work can be transformed into heat, such as might be experienced by rubbing your hands together to warm them up. Heat energy (such as steam engines) can be used to do work (such as pushing a train down the track). They are also related forms, in that one can be transformed into the other. Heat and WorkHeat and work are both forms of energy. Thermodynamics can be roughly encapsulated with these five (5) topics: The term itself clearly suggests what is happening - "thermo", from temperature, meaning energy, and "dynamics", which means the change over time. Thermodynamics is the study of energy changes accompanying physcial and chemical changes. are clearly physical events that also have a chemical nature to them. Certainly changes in energy - however measured, whether it be heat, light, work, etc. Physics concerns itself heavily with the mechanics of events in nature. The scientific discipline that intersects the areas of chemistry andphysics is commonly known as physical chemistry, and it is in that area that a thorough study of thermodynamics takes place.
