Measuring Temperature: Practical vs Theoretical Approaches

In summary, the conversation revolves around measuring temperature without using a thermometer, specifically in the context of a car bulb. Suggestions and questions are being exchanged, including clarifying the definition of a thermometer and exploring the concept of black body radiation. It is suggested to clarify the context and purpose of the temperature measurement, as well as whether a contact or non-contact method is preferred.

Hi everyone, How do u measure temperature, let's say of a car bulb without using a thermometer?


Your ideas are all welcomed.
Thanx

What is the context of your question? Is this for schoolwork?

Berkeman's question notwithstanding, do you know anything about black body radiation? I guess it'd probably be best to dial it back a bit and follow-up from dlgoff's question and ask if you are approaching this more from a practical or theoretical perspective, and whether or not you mean contact vs non-contact.

1. What is the difference between Celsius and Fahrenheit?

Celsius and Fahrenheit are two different temperature scales. The main difference between them is the reference points. The Celsius scale uses the freezing point of water as 0 degrees and the boiling point of water as 100 degrees, while the Fahrenheit scale uses 32 degrees and 212 degrees as the respective reference points.

2. How is temperature measured?

Temperature is measured using a device called a thermometer. A thermometer typically contains a liquid or gas that expands or contracts with changes in temperature. The expansion or contraction is then translated into a numerical value on a scale, which indicates the temperature.

3. What is the unit of measurement for temperature?

The most commonly used unit of measurement for temperature is degrees Celsius (°C) or degrees Fahrenheit (°F). However, there are other units such as Kelvin (K), which is used in scientific research and is based on the absolute zero point of temperature.

4. Can temperature be negative?

Yes, temperature can be negative. In the Celsius scale, temperatures below 0 degrees are considered negative, while in the Fahrenheit scale, temperatures below 32 degrees are considered negative. In both scales, negative temperatures indicate temperatures below the freezing point of water.

5. What factors can affect temperature measurement?

There are several factors that can affect temperature measurement, such as the type of thermometer used, the accuracy of the thermometer, the location and environment where the measurement is taken, and the material being measured. Other factors, such as human error and external heat sources, can also affect temperature measurement.
