the gas‚ liquid‚ or solid phase. In order to separate or remove one or more of the component from its original mixture‚ it must be contacted with another phase. The two-phase pair can be gas-liquid‚ gas-solid‚ liquid‚ or liquid-solid. Absorption When the two contacting phases are a gas and a liquid. A solute A or several solutes are absorbed from the gas phase into a solid phase. Distillation A volatile vapor phase and a liquid phase that vaporizes are involved. Liquid-liquid Extraction

Water Traps and Pigtail Siphons A water trap is a device that allows gas and air to pass but holds back water. Pigtail Siphons Industrial factories utilize steam as a pressurized fuel for energy consumption. This steam needs to be regulated by a gauge‚ but the gauge must have a way of being safe from the powerful heat and pressure of the steam itself. This is where pigtail siphons (or siphons) come in. Function Pigtail siphons are looped pipes filled with water that are placed in piping configurations

Evaporation Several factors determine how fast a sample of liquid will evaporate. The volume of the sample is a key factor. A drop of water takes less time to evaporate than a liter of water. The amount of energy supplied to the sample is another factor. In this lab‚ you will investigate how the type of liquid and temperature affect the rate of evaporation. Problem: How do intermolecular forces affect the evaporation rates of liquids? Pre-Lab: Read the ENTIRE LAB first then answer the following

also two different containers to place the creatures in. Lastly‚ the person performing the experiment should choose two different liquids to place the creatures in. The first step in the actual experiment is to open the two packages containing the polymer creatures and then placing each of them aside for later. Next‚ fill the the two containers with the two different liquids of choice‚ which in this case is water and vinegar. Finally‚ after filling the containers‚ place one of the two polymer creatures

possessed many advantages and disadvantage‚ both from the process itself and from the final part produced. Observing the process step by step it was noted that the tasks carried out by the operator were not very difficult (i.e compacting sand‚ pouring liquid metal) and so giving the advantage of only requiring a low skill level. However‚ although the process did not involve a large amount of skill it was observed to be very labour intensive and took a long time to complete one cycle of the process (around

generates through a novel microfluidic phenomenon. Reverse electrowetting is a process by which liquid motion is converted into electrical energy. It can generate a power up to 103Wm−2‚ by this technology. Reverse electrowetting (REWOD) concept At first‚ The principle of electrowetting is defined in here. The shape of a liquid droplet on a solid layer is characterized by the contact angle θ between the liquid and the solid layer (Figure 1). Electrowetting is the phenomenon whereby an electric field

Longitudinal and transverse waves Sound is transmitted through gases‚ plasma‚ and liquids as longitudinal waves‚ also called compression waves. Through solids‚ however‚ it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure‚ causing local regions of compression and rarefaction‚ while transverse waves are waves of alternating shear stress at right angle to the direction of propagation

The simulation and analysis of liquid droplets with respect to heat capacity and droplet size Abstract Define Using Molecular dynamic simulation a cluster of particles was modelled and their behaviour analysed with respect to temperature change. As proof of a specific state i.e. solid‚ the Mean squared displacement was calculated and illustrated with respect to time. This occurred for varying temperatures. From the internal energy of the system per time step‚ the heat capacity was determined

The physical properties‚ including the boiling point‚ density‚ and refractive index were measured for unknown liquid #16. The infrared (IR) spectrum of the compound was also taken. Based on the data collected‚ it was determined that the compound was likely to be salicylaldehyde. Introduction The purpose of this experiment was to determine the identity of an unknown organic liquid by measuring some of its physical properties. The properties were then compared to those of known compound to make
