How thermometer is an example of Zeroth Law thermodynamics?
How thermometer is an example of Zeroth Law thermodynamics?
The thermometer may be the most well-known example of the zeroth law in action. For example, say the thermostat in your bedroom reads 67 degrees Fahrenheit. This means that the thermostat is in thermal equilibrium with your bedroom.
What is the law of thermometer?
A thermometer measures the temperature of a body which is a direct implication from the zeroth law of thermodynamics. The thermometer and the body come into thermal equilibrium with each other.
How do thermometers work?
Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. Numbers are placed alongside the glass tube that mark the temperature when the line is at that point. The other type of common thermometer is a “spring” thermometer.
Who proposed Zeroth Law of Thermodynamics?
Ralph H. Fowler
Zeroth law of thermodynamics is one of the four laws of thermodynamics. The credit for formulating the law goes to Ralph H. Fowler.
Who created the Zeroth Law of Thermodynamics?
The name ‘zeroth law’ was invented by Ralph H. Fowler in the 1930s, long after the first, second, and third laws were widely recognized. The law allows the definition of temperature in a non-circular way without reference to entropy, its conjugate variable.
What is the importance of zeroth law of thermodynamics?
Significance: This law signifies that temperature is a fundamental indicator of thermal equilibrium. If two bodies of the same temperature come in contact with each other then there is no net exchange of heat and those two bodies are said to be in thermal equilibrium.
Why zeroth law of thermodynamics is called so?
The Zeroth law is called so because the first two laws of thermodynamics were established before, and they were named before. It was later found that zeroth law was more fundamental than the other laws of thermodynamics, that is the reason why it is called zeroth law of thermodynamics.
