Objective 1. To demonstrate the relationship between the pressure and temperature of saturated steam in equilibrium with water. 2. To determine the vapour pressure curve. Introduction Properties of a fluid can change when heat and work are applied to it. There’s an interchange between the fluid and its surroundings when heat and work are applied according to the study of thermodynamics. Substances such as gases and vapors are often referred as P-V-T substances. Theory: An ideal gas

After a holding period of 18 hours for winter captured crabs and a period of 30 hours for summer captured crabs‚ all individuals were transferred to containers with experimental temperature and salinity levels to begin the experiment. To observe changes due to salinity concentrations over the 48-hour period‚ groups of crabs were exposed to one of the eight salinity treatments‚ and temperature treatments were held constant at 5°C or 15°C to resemble winter or summer field conditions

In the society described in Jane Austen ’s Pride and Prejudice‚ money was as much a social currency as it was a means of exchange for goods and services. Money was often commensurate with social rank‚ yet there was a feeling against parvenus who worked for their fortunes.
