C. From carbon dioxide in the atmosphere
Answer:
Differences in their boiling points
Explanation:
When crude oil is distilled and separated into categories, the categories are characterized by the differences in their boiling points.
At different boiling points, each of the fraction will separate out.
- Crude oil is made up of different fractions of hydrocarbons.
- As the chain length of the hydrocarbon increases, the volatility reduces and boiling point increases.
- Components with short carbon lengths rises out from the column first and are cooled and extracted.
- The categories are thereby, classified based on differences in their boiling points.
Answer:
The classic symptoms of asthma include wheezing, coughing, tightness in your chest, and feeling short of breath. But other conditions — like allergies, chronic obstructive pulmonary disease (COPD), sleep apnea, and post nasal drip — can trigger the same problems.
