DETERMINATION OF SPECIFIC HEAT CAPACITY AND COOLING RATE OF ENGINE OILS
Abstract
This study was conducted to determine the specific heat capacity and cooling rate of different engine oils. The experiment involved heating samples of engine oils to a known temperature and monitoring their cooling process over time. The specific heat capacity was determined using the principle of heat exchange, while the cooling rate was calculated from temperature-time data based on Newton's law of cooling. The results showed that different engine oils possess varying thermal properties, influencing their ability to absorb and dissipate heat. Oils with higher specific heat capacity cooled more slowly because they retained heat for longer periods. The findings provide valuable information for selecting suitable engine oils capable of improving engine cooling efficiency and overall performance.
