WebThe boiling point of a liquid is the temperature at which its vapour pressure equals the atmospheric pressure of its surroundings. The liquid transforms into a vapour at this temperature. Definition: The temperature at which a … WebDiesel fuel is a mixture of hydrocarbons—with boiling points in the range of 150 to 380°C—which are obtained from petroleum. Petroleum crude oils are composed of hydrocarbons of three major classes: (1) paraffinic, (2) naphthenic (or cycloparaffinic), and (3) aromatic hydrocarbons. Unsaturated hydrocarbons (olefins) rarely occur in the crude.
WebLight distillate is one of the more important fractions, and its products have boiling points around 70-200°C. Useful hydrocarbons in this range include gasoline, naphta (a chemical feedstock), kerosene, jet fuel, and paraffin. These products are highly volatile, have small molecules, have low boiling points, flow easily, and ignite easily. Web(b) At 0°C, the water is at its freezing point, hence both solid and liquid phases are observed. (c) At 100°C, the water is at its boiling point, hence both liquid and gaseous states of water (water vapour) are observed. 6. Give two reasons to justify – (a) Water at room temperature is a liquid.
