At what level are C and F the same?

pressure (even around room temperature) and then extend the line to find the temperature where the pressure should be zero. Kelvin figured that this would be a much more natural place for “zero” to be, and he carefully measured it (by extending the line) to be around -273.

Absolute zero can be defined as the temperature at which matter does not move. … Because the pressure in this experiment is caused by the movement of a gas, the pressure would cease to exist when the gas stops moving (a.k.a. absolute zero).

Now the zero in absolute zero makes sense: Absolute zero is the temperature at which the particles in a substance are essentially motionless. There’s no way to slow them down further, so there can be no lower temperature.

Key Takeaways: When Does Fahrenheit Equal Celsius? Celsius and Fahrenheit are two temperature scales. The Fahrenheit and Celsius scales have one point at which they intersect. They are equal at -40 °C and -40 °F.

273.

The Celsius and Fahrenheit scales were both built around water, either the freezing point, the boiling point or some combination of water and a chemical. The Kelvin temperature scale is used by scientists because they wanted a temperature scale where zero reflects the complete absence of thermal energy.

The Four Types of Temperature Scales

• Fahrenheit Scale. ••• The Fahrenheit scale of temperature is the common form of temperature measurement used in the United States and some parts of the Caribbean. …
• Celsius Scale. ••• Outside the United States, most of the world uses the Celsius scale to measure temperatures. …
• Kelvin Scale. ••• …
• Rankine Scale. •••
