MELTING POINT AND BOILING POINTS OF ORGANIC COMPOUNDS ABSTRACT The properties of organic compounds depend on their chemical structures. Intermolecular forces of attraction affect physical properties such as melting and boiling point. Through the Thomas Hoover apparatus‚ the melting point of 8 test compounds was determined. Salicylic acid exhibited the highest melting point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting point. Boiling point

experiment was to investigate the effects of salt type and concentrations on the rate of heating and the boiling point. Then from this data make a conclusion which salt type and concentration is the most energy efficient at heating water to its boiling point. It was hypothesised that highest concentration of MgCl2 was going to be the most energy efficient at heating the solution to its boiling point. This is because MgCl2 has the lowest specific heat capacity thus will use the least amount of energy

Evaluating Truth and Validity Exercise Alfred Bishop PHL/458 May 07‚ 2015 Patricia Anderson Evaluating Truth and Validity Exercise The arguments I will choose to evaluate for truth and validity will be taken from the Applications list 12.2 (a.-y.) at the end of Ch. 12 in The Art of Thinking. I will start with exercise j and the premise that “power must be evil because it can corrupt people”. First of all‚ I would check the argument for any hidden premises making sure that it was stated

Many find it interesting to glimpse inside the lives of famous thinkers in an effort to understand where such thought and intelligence is rooted. Famous thinkers have little in common with what makes them reach their level of achievement (Goodman & Fritchie‚ 2011). In that tone‚ here is a peek into the routines and rituals of Martin Luther King Jr. and Cornel West that writers‚ philosophers‚ and statesmen have depended on to keep their work on track and their thoughts flowing. Whether you need inspiration

Fuels Research Question How does the chain length of an alcohol (1‚ 2‚ 3‚ 4 or 5 carbon atoms) affect its boiling point (°C)‚ determined using micro boiling point apparatus (heating the liquid in a capillary tube placed in paraffin oil)? The alcohols tested will be methanol (1 carbon atom)‚ ethanol (2 carbon atoms)‚ propan-1-ol (3 carbon atoms)‚ butan-1-ol (4 carbon atoms) and pentan-1-ol (5 carbon atoms). Variables Variable Description Independent This is the variable that will change; the chain

information about boiling water. If you cover the tin and allow the water and air to cool down‚ the air will cool and contract‚ lowering the pressure in the tin. If it lowers enough‚ the partial vacuum will collapse the walls of the can! The boiling point definitely reduces with air pressure. There is a famous demonstration where boiling water or coffee is drunk‚ the trick is it was in a vacuum chamber where it boiled at room temperature. The actual definition of the boiling point of water is the

BOILING AND CONDENSATION BOILING • Phase change phenomenon where in transformation of liquid to vapour occurs at the saturation temperature of the fluid. It occurs at a solid/liquid interface due to convection heat transfer from the solid and usually occurs at surface temperatures higher than the saturation temperature of the fluid Agitation of fluid by vapor bubbles provides large convection coefficients Modified Newton’s law of cooling qs’’ h Ts Tsat Te • • • BOILING – CLASSIFICATON
