various components (called fractions)‚ is to do it using the differences in boiling temperature. This process is called fractional distillation. You basically heat crude oil up‚ let it vaporize and then condense the vapour The various components of crude oil have different sizes‚ weights and boiling temperatures; so‚ the first step is to separate these components. Because they have different boiling temperatures‚ they can be separated easily by a process called fractional distillation. The steps

Why does snow melt in the sun at temperatures below freezing? The rate of snow melt is dependent on energy availability‚ which is mostly in the form of radiation. Cold snowpacks have a negative energy balance‚ but warming causes the snowpack to become isothermal and additional energy results in positive energy balance and melt. Daily snow melt in forested areas is considerably less than melt in open areas‚ as forests protect the snow cover from solar radiation and wind. Canopy warming can increase

Chemistry Caloric Content of Food Date Submitted: April 1‚ 2012 Date Performed: April 1‚ 2012 Lab Section: Chem-180-DL1 Purpose: The purpose of this lab was to measure the energy content of three different food items using the change in water temperatures from the heat of the food. Another purpose was to take the information acquired and become familiar with energy units used in food such as calories and joules. Procedure: The first step in this experiment was to weigh and record an empty 100mL

boiling point. This process works best when the boiling points of the components are significantly different (simple distillation). Components can be effectively separated by a one-step vaporization. Fractional distillation is used when the boiling temperatures are very similar and the vapour produced is a combination of the mixture. The addition of a fractionating column allows numerous small distillations to occur within the column as the vapour rises towards the condenser. This experiment will
