Final answer:
Temperature light or gauge indicates the temperature of a system or device, like in cars for engine temperature or in household appliances for temperature setting.
Step-by-step explanation:
The temperature light or gauge indicates the temperature of a system or device. It is commonly found in various contexts, such as in cars to monitor the engine temperature or in household appliances to indicate the temperature setting. The temperature can affect the performance and safety of the system, so the gauge provides a visual representation of the temperature level.
In a car, for example, the temperature gauge measures the heat of the engine coolant. If the needle on the gauge points towards the high temperature range, it can indicate an overheating engine, which may require immediate attention. On the other hand, a low temperature reading could mean the engine is not warming up properly.
Similarly, household appliances like ovens or refrigerators have temperature controls. As you adjust the temperature setting, the gauge indicates the selected temperature. This allows you to monitor and maintain the desired temperature for cooking or preserving food.
