# Pressure and temperature relationship in atmosphere of love

### Mrs. Deringer - Air Pressure

Weather is the current state of the atmosphere and is determined by factors like temperature, pressure and humidity. These factors that cause. Besides solid Earth and ocean tides, atmospheric pressure variations are one of the The atmosphere acts on surface gravity through two effects: first, a direct . The ideal gas equation gives us relations between temperature T, density ρA and . which are respectively the load radial and potential Love numbers (Hinderer. In this lesson, we will discover why the wind blows and what causes a hot air balloon to rise, a couple of the applications of Charles' Law that.

## The ideal gas law – why bubbles expand if you heat them

It is an intuitive idea that bubbles of air will expand if you heat them, as long as the pressure remains constant. It is also a fundamental component of the ideal gas laws, first written down in the early 19th century by the French natural philosopher Joseph Louis Gay-Lussac. He was working on the relationship between the volume and temperature of a gas, building on work carried out several decades earlier by the inventor and mathematician Jacques Charles who had shown that volume and temperature were proportional — heat a gas and its volume will increase and vice versa, as long as the pressure remains constant.

The first piece of the ideal gas puzzle came in the 17th century. Robert Boyle had been carrying out experiments with air, which he proposed was full of particles connected by tiny invisible springs. He found that the pressure of a gas had an inverse relationship to its volume. If the volume doubled, its pressure halved and vice versa, when the temperature is held constant.

In short, the ideal gas law shows the relationship between the four properties of a gas that you need to know in order to predict how it will behave: It is "ideal" because the law is a model that assumes the particles are infinitely small points and do not interact with each other. All collisions between ideal gas particles are elastic, which means they do not lose any energy when they rebound off each other.

In practice, real gas particles do have measurable sizes and sometimes attract or repel each other.

Nevertheless, the ideal gas equation is a highly successful way to understand how gases shift and change depending on their surroundings. Oxygen has a molecular weight of 16 so an O2 molecule has a molecular weight of Given the mixture of gases found in air the average molecular weight of air is around Water is made up of two hydrogen and one oxygen atoms H2O.

Hydrogen is the lightest element and has a molecular weight of one. Water is a very light molecule and much lighter than the average weight of the molecules found in air.

Moist Air In the real world the air always contains some moisture. The addition of water vapour to a mass of air makes it less dense. Whilst this may appear a bit odd at first this occurs because the molecular mass of water 18 is less than the molecular mass of air The simple correction using only the local pressure measurement cannot take into account the large scale pressure structures existing over the whole surface of the Earth, and is therefore not sufficient to estimate either the induced global deformation and mass redistribution of the Earth or the Newtonian direct attraction induced by regional km around the gravimeter mass variations.

The purpose of this paper is to estimate surface gravity variations induced by the atmospheric circulation with a physical approach and to propose an operational modelling using global atmospheric data provided by meteorological centres. As a first step, we determine and describe the physics of the source the atmosphere and the transfer functions Newtonian and elastic atmospheric Green's functions. For the computation of the gravitational attraction, we consider different models for the atmosphere.

We then describe the superconducting gravimeter observations and their processing. The next section is devoted to the determination of the optimal model for computing the atmospheric loading; special attention is paid to the ocean response to pressure.

We show that pressure variations are characterized by large scale structures with wavelengths greater then km. We recall that the hydrostatic equilibrium hypothesis is verified for periods larger than 12 hr Greenso the estimation of atmospheric density variations with altitude, as a function of surface pressure and temperature conditions with the help of the hydrostatic equilibrium equation, is adequate for our atmospheric data.

The first data set, provided by the NCEP, consists of surface pressure data with a sampling rate of 6 hr and a spatial resolution of 2. These NCEP reanalysis data are provided using a state-of-the-art analysis system to perform data assimilation from to the present. The time sampling rate is the same as the NCEP reanalysis series 6 hr. The spatial sampling is 1.

Degrees 1 and 3 which include S1 and Sa diurnal and annual thermal waves are shown to be variable in time with a seasonal component. For periods exceeding a few hours, the atmospheric circulation is principally governed by horizontal displacements Green The hydrostatic equilibrium is verified and we can use the corresponding equation to estimate density variations with altitude as a function of surface parameters temperature and pressure.

There is also a relationship between the horizontal wavelength and the period of atmospheric variations Green High frequency pressure variations are coherent on small scale surfaces whereas low frequency atmospheric structures are coherent on large scale surfaces.
