In the preparation of a TLC plate for the development, the result of making small spots needs to be explained. Concept Introduction: Chromatography is the best method of separation of components from the mixture as it gives most accurate results compare to other methods. In this method the mixture must be dissolved in certain fluid that is called as mobile phase. This mobile phase carries different components of mixture on the structure holding another material. This material is known as stationary phase. There are various types of chromatography methods such as column chromatography, thin layer chromatography, gas chromatography etc.

Question

The fire releases 2.80 x 107 Joules of heat energy for each liter of oil burned. The water starts out at 24.5 °C, raising the water's temperature up to 100 °C, and then raises the temperature of the resulting steam up to 325 °C. How many liters of water will be needed to absorb the heat from the fire in this way, for each 1.0 liter of crude oil burned? 4186 J/(kg°C) = heat of water 2020 J/(kg°C) = heat of steam 2,256,000 (i.e. 2.256 x 106) J/kg = latent heat of vaporization for water (at the boiling point of 100 °C).
