Write an essay describing the laws of thermodynamics for kids

With the valve shut the boiler is further heated and the boiler pressure is raised to 15 bar. This results to an increase of the number of microstates which results into entropy increase.

This leads to the deduction that energy used cannot be completely converted to the targeted work hence the negative entropy evinced sometimes. When the barrel of oil is converted to some form of work and maybe some wasted as heat, it is the heat that perpetually results from the work that the oil is doing.

In this test the air-source evaporator is used. The oil cannot be recycled because the increase in the microstates during its combustion takes up the heat that is produced making the system consist of molecules at random motion in a balanced state.

The filler opening 6 is used to pour water into the boiler. Dublin Institute of Technology The water to be heated 19 comes from the cold water supply. It passes through a variable area flow meter 16 before passing through a cooling coil within the compressor.

Describe the laws of thermodynamics - Essay Example

The boiler temperature can be read from the digital display 11 fitted into the switch box. Select the air evaporator by pressing the evaporator change over switch down. This means that as the fuel is converted through the system, it increases the heat at the surrounding leading to an increased motion of molecules.

The refrigerant condensate from the condenser accumulates in the liquid receiver. In the condenser there is heat transfer to the water that is to be heated. If less than zero it means that the process is not spontaneous in the stated direction but rather in the opposite direction.

Thermocouples on the water circuit allow three required temperatures to be displayed on the temperature indicator 3. This law is thus based on the basic principle governed by the law of conservation of energy. Repeat steps 4 and 5 until the desired number of tests have been conducted.

This is to ensure that there is no air in the boiler. Thermodynamics Laboratory Manual Heat Pump 1 2 3 7 4 5 6 Temperature indicator Evaporator pressure Temperature selector High pressure cut-out switch Condenser pressure 12 Evaporator change over switch 14 Thermostatic expansion valve 15 Refrigerant flow meter 16 Compressor 17 Air-source evaporator 18 Heated-water outlet 13 Water-source evaporator water flow meter 10 Condenser water flow meter 11 Main power switch 9 8 Water-heating condenser Electric power meter Condenser liquid receiver Water-source evaporator 19 Inlet of water to be heated The main components involved in this test are described briefly here.

This is an indication that energy is lost or not channeled for its right course leading top wastage.

The unit is switched on at the master switch 9.Thermodynamics is a branch of physics that studies the effects of changes in temperature, pressure, and volume on physical systems at the macroscopic scale by analyzing the collective motion of their particles using statistics. The laws of thermodynamics just clearly put into much clearer terms the laws of life.


Since thermodynamics is a science that deals with energy and energy transformations as well as the resulting work it produces, it has practical applications in. describe the laws of thermodynamics.

Explain how these scientific laws apply to energy use, energy conversions, and the need for energy efficiency. Describe the pros and cons of the following energy types, writing 1 paragraph for each.

The Laws of Thermodynamics essay

Published: Fri, 28 Apr This writing assignment explains some essential ideas about the Laws of Thermodynamics and how oranges exist given the Law of Thermodynamics, along with ideas of entropy.

The drain valve (1) can be used to drain the vessel. An electric heater (2) is bolted into the floor of the boiler in such a way that the heating. In statistical thermodynamics, Boltzmann's equation, is a possibility equation relating the Entropy S of an ideal gas to quantity W, which is the number of micro-states corresponding to a given macro-state.
