Question

What are the ordinary and absolute temperature scales in the SI and the English system?

Short answer

Question: Identify the ordinary and absolute temperature scales in both the SI and English systems. Answer: In the SI system, the ordinary temperature scale is Celsius, and the absolute temperature scale is Kelvin. In the English system, the ordinary temperature scale is Fahrenheit, and the absolute temperature scale is Rankine.

Step-by-step solution

Identifying the SI Temperature Scales

In the SI system, there are two temperature scales: the Celsius scale (used for ordinary temperature measurements) and the Kelvin scale (used for absolute temperature measurements). The Celsius scale represents the ordinary temperature scale and is based on the freezing point of water (0°C) and boiling point of water (100°C) at 1 atmosphere of pressure. The Kelvin scale, as the absolute temperature scale, starts at absolute zero (0 K), which is considered the lowest possible temperature.

Identifying the English Temperature Scales

In the English system, there are two temperature scales as well: the Fahrenheit scale (used for ordinary temperature measurements) and the Rankine scale (used for absolute temperature measurements). The Fahrenheit scale is based on the freezing point of water (32°F) and boiling point of water (212°F) at 1 atmosphere of pressure. The Rankine scale represents the absolute temperature scale, starting at absolute zero (0 °R).

In Summary

In both the SI and English systems, there are separate temperature scales for ordinary and absolute measurements: - SI System: Celsius (ordinary) and Kelvin (absolute) - English System: Fahrenheit (ordinary) and Rankine (absolute)
