Calculations/Analysis Through this lab‚ we are now able to calculate the molar heat of combustion for paraffin‚ since we have the difference of the mass in candle before/after and the periodic table of elements (for converting g to moles of paraffin). Molar heat of combustion = (kJ of heat)/(mole of fuel) However‚ we do not know how much heat was released nor the mole of fuel (paraffin). In order to find the amount of heat released‚ we use the formula: g=mcΔT. Here‚ g represents the heat‚ m represents the mass

Heat engine lab Intro: when an engine runs‚ it pumps pistons that move up and down and provide energy to the engine to it to go. These pistons move because of pressure and heat. This work done on the system is not only mechanical but its also thermodynamic. When a piston undergoes one full cycle its displacement is zero because it comes back to its resting place. This means that its net thermodynamic work to be done should also be zero‚ as well as its total internal energy. In order to test this

Vapor Pressure and Heat of Vaporization Introduction: Evaporation is the process of a liquid becoming vaporized. When a liquid is placed into a confined space some of the liquids will evaporate. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules. During the evaporation process of the liquid‚ new gas molecules exerts pressure in the sealed container‚ while some of the gas condenses back to the liquid state. If the temperature inside

1. Shell and Tube Heat Exchanger – Working Principle The shell and tube heat exchanger comprises of two major things as its name state "Shell and Tube". The shell is a major vassel with quantities of tube inside it (Jalmood‚ n.d). Shell and tube heat exchangers are helpful for pressurized application. Heat is exchanged between the liquid in the tubes and the liquid inside the shell. Configuration of the tube pack is such that‚ all the section sides of the tube could be joined with a typical header

Peanut husks‚ one of the biggest food industry waste products‚ could be used to extract environmentally damaging copper ions from waste water‚ according to researchers in Turkey. Writing in the Inderscience publication the International Journal of Environment and Pollution‚ the team describes how this readily available waste material can be used to extract toxic copper ions from waste water. The discovery offers a useful alternative to simple disposal of this ubiquitous food industry waste product
