What is thermometer in thermodynamics?

Some common thermodynamic meters are: Thermometer – a device which measures temperature as described above. The volume will then measure pressure, by the ideal gas equation P=NkT/V . Calorimeter – a device which measures the heat energy added to a system.

What is the working principle of thermometer?

These liquid thermometers are based on the principal of thermal expansion. When a substance gets hotter, it expands to a greater volume. Nearly all substances exhibit this behavior of thermal expansion. It is the basis of the design and operation of thermometers.

Which law of thermodynamics is the basis of why a thermometer can read the temperature of another object?

The zeroth law of thermodynamics. When two systems are each in thermal equilibrium with a third system, the first two systems are in thermal equilibrium with each other. This property makes it meaningful to use thermometers as the “third system” and to define a temperature scale.

How does the first law of thermodynamics work?

The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is ΔU = Q − W.

How does thermometer work relate it to the zeroth law of thermodynamics?

The zeroth law of thermodynamics states that if two bodies are each in thermal equilibrium with some third body, then they are also in equilibrium with each other.

How does a thermometer work thermal equilibrium?

A thermometer measures its own temperature. It is through the concepts of thermal equilibrium and the zeroth law of thermodynamics that we can say that a thermometer measures the temperature of something else, and to make sense of the statement that two objects are at the same temperature.

Which law of thermodynamics is used in thermometer?

The Zeroth Law of Thermodynamics
The Zeroth Law of Thermodynamics defines temperature and makes thermometers possible.

What is a thermometer in physics?

A thermometer is used to measure how hot or cold something is. There is a number scale showing temperature going from cold at the bottom to hot higher up.

How does the first law of thermodynamics extend the principle of conservation of energy?

-The first law of thermodynamics extends the principle of conservation of energy to include heat as well as mechanical energy. -The amount of heat added or removed from a thermodynamic system depends only on the initial and final states of the system.

On what law is the first law of thermodynamics based?

the law of conservation of energy
The first law of thermodynamics is based on the law of conservation of energy, which states that energy cannot be created or destroyed, but can be transferred from one form to another.

How the first law of thermodynamics is explained in other references?

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. In other words, energy cannot be created or destroyed.

How does thethermometer work on first law of thermodynamics?

Thermometer does not work on first law of thermodynamics. Thermometer works on zeroth law of thermodynamics which states that “If body A and body B are in thermal equilibrium, and body B and body C are in thermal equilibrium than body A and C will also be in thermal equilibrium “.

What is work and heat in the first law of thermodynamics?

The First Law of Thermodynamics Work and heat are two ways of transfering energy between a system and the environment, causing the system’s energy to change. If the system as a whole is at rest, so that the bulk mechanical energy due to translational or rotational motion is zero, then the

What is the working principle of a thermometer?

The working principle of a thermometer is the Zeroth Law of thermodynamics. The Zeroth law states that When two bodies are in thermal equilibrium with some third body, then the all three bodies are in thermal equilibrium with each other.

How does a thermometer work according to the zeroth law?

Answer Wiki. Thermometer works on zeroth law of thermodynamics which states that “If body A and body B are in thermal equilibrium, and body B and body C are in thermal equilibrium than body A and C will also be in thermal equilibrium “.
