Thermodynamics study about the interchange of heat and work between a system and the surroundings which occurs when the system undergoes a process. Thermodynamic also concerned about the changes in the properties of fluid. Most thermodynamics substances such as gases and vapours are often referred as P-V-T substances. An ideal gas obeys the equation of state that relates the pressure, specific volume or density, and absolute temperature with mass of molecule and the gas constant, R. However, real gas does not absolutely obey the equation of state. A few modifications on the ideal gas equation of state allow its application in the properties of real gas. When energy is added within water, the increasing of activities among the molecules caused the increase in the number of molecule escape from the surface until an equilibrium state is reached. The state of equilibrium depends on the pressure between the water surface and steam. The lower the pressure, the easier the molecules leaving the water surface and thus less energy is required to achieve the state of equilibrium (boiling point). The temperature where equilibrium occurs at a given pressure level is called saturated temperature. The pressure where equilibrium occurs at a given temperature is called saturated pressure. Marcet Boiler is used to investigate the relationship between the pressure and temperature of saturated steam in equilibrium with water at all temperature. The conducted experiment provides us a clear image on the progressing in between pressure, time and temperature. As time increased, the increased temperature energized the molecules of the water and thus, pressure became higher until the state of equilibrium.
With higher temperature, low voltage
Pressure safety valve-are the valve who are designed such that it can control the pressure , like in the water blowers etc,and Temperature safety valve are those who are used to regulate the temperature like, in water boilers.

Saturated steam occurs when steam and water are in equilibrium. If you have a closed container of water and heat it, above 100 celsius the steam pressure will start to rise, and as the temperature continues to rise, the pressure will go on rising. What is happening is that steam is being evolved to match the temperature (steam tables will give this relation) and the steam conditions are said to be saturated because if the pressure is raised by external means, some of the steam will start to condense back to water.If the steam pressure is held at a lower level than that achieved at saturation, by taking steam off to feed a turbine or other steam usage, there is effectively an excess temperature for that pressure, and the steam is said to be superheated. It in fact then becomes dry, and behaves as a gas. The amount of superheat can be quantified as so many degrees of superheat (celsius or fahrenheit).Turbine designers want steam to be superheated before reaching the turbine, to avoid condensation causing blade erosion, and steam producing boilers in power plants are designed to produce superheated steam. In plants where no turbines are used, only satured steam is normally generated.In heating applications, saturated steam is preferable, because it has a better energy exchange capacity. Superheated steam must cool down, and become saturated steam, before condensing in a heat exchanger. Also, superheated steam is a thermal insulator, like air.That is why it is necessary to direct superheated steam through a desuperheater before using the steam in heating applications.
hye... pls answer these question... i want submit my assigment tomorrow..........
The Marcet Boiler is used to investigate the relationship between the pressure and temperature of saturated steam in equilibrium with water at all pressure levels between the atmospheric pressure and 1100 kPa.
The pressure vs temperature graph shows that there is a direct relationship between pressure and temperature in the system. As temperature increases, pressure also increases, and vice versa. This relationship is known as the ideal gas law.
Gas pressure and temperature have a direct relationship. If the pressure is raised, then the temperature will also raise, and vice versa.
The relationship between water vapor pressure and temperature is direct and proportional. As temperature increases, the vapor pressure of water also increases. Conversely, as temperature decreases, the vapor pressure of water decreases. This relationship is described by the Clausius-Clapeyron equation.
The graph illustrates the relationship between vapor pressure and temperature. As temperature increases, vapor pressure also increases.
The relationship between temperature and pressure is that they are directly proportional in a closed system. This means that as temperature increases, pressure also increases, and vice versa. This relationship is described by the ideal gas law, which states that pressure is directly proportional to temperature when volume and amount of gas are constant.
According to Gay-Lussac's Law, the relationship between pressure and temperature is direct. This means that as the temperature of a gas increases, its pressure also increases, and vice versa.
The vapor pressure vs temperature graph shows that as temperature increases, the vapor pressure also increases. This indicates that there is a direct relationship between vapor pressure and temperature, where higher temperatures lead to higher vapor pressures.
In an ideal gas, the relationship between pressure and temperature is described by the ideal gas law, which states that pressure is directly proportional to temperature when volume and amount of gas are constant. This means that as temperature increases, so does pressure, and vice versa.
The vapor pressure graph shows that as temperature increases, the vapor pressure also increases. This indicates a direct relationship between temperature and vapor pressure, where higher temperatures result in higher vapor pressures.
The relationship between pressure and volume (apex)
The relationship between water temperature and pressure is that as water temperature increases, its pressure also increases. This is because as water heats up, its molecules move faster and spread out, causing an increase in pressure. Conversely, as water cools down, its pressure decreases.
