Figure 1: Examples of heat If an equal amount of heat is added to each object, they will both increase in temperature. Figure 2: Increases in temperature The smaller brake disc will end up hotter than the engine block, even though they have both received the same amount of heat. The temperature, or the intensity of heat, is higher in the brake disc. It will feel hotter than the cylinder block. Automotive technicians need to measure temperature, to decide if systems are working correctly. Figure 3: Measuring temperatures in systems Safety First Measuring temperature can be DANGEROUS! don’t hot objects or liquids hot can burn your skin hot liquids can splash and burn your face and eyes. Always wear suitable Personal Protective Equipment for the job, such as face mask or safety glasses, and skin protection like gloves and overalls. Figure 4: Worker with safety equipment Temperature scales Temperature is measured on a scale based on two common effects of temperature: the freezing temperature of water the boiling temperature of water. Celsius temperature scale The Celsius temperature scale is divided into 100 parts between 0 and 100. Each section is called a degree. the freezing point of water is called 0 degrees, or 0o C.
