Here are the solutions to Activity 3.3: 1. Match the property in the left column to the correct description in the right column: Flash point: Minimum temperature at which an oil will ignite momentarily. Thermal stability: To resist breakdown at high temperatures. Fire point: Lowest temperature at which an oil will ignite and burn for at least five seconds. Oiliness: Maintaining an unbroken lubricating film between rubbing surfaces. Viscosity: Gives an indication of the thickness or thinness of an oil. 2. List five factors to consider when choosing a lubricant: Operating temperature* Operating pressure/load* Speed of moving parts* Environmental conditions* (e.g., presence of water, dust) Type of machinery/application* That's 2 down. 3 left today — send the next one.
