Wildlife volunteering is a broad topic and there really is something for everyone. Some projects involve really getting your hands dirty in the jungle, but if this does not sound like your thing there are also plenty of other ways to get involved.
EXPERIMENT 2: Recrystallization and Melting Point. Melting Point is: â¢a constant physical property of a solid (the temperature at which it turns to a liquid) â¢reported in the lab as a melting point range (usually 1â2 ËC wide), not as a single temperature.
More energy is needed to separate them than short chain molecules which have only weak forces of attraction for each other. QUES: Name some of the compounds in the table and state whether the compound will be a gas, liquid, or solid state at room temperature (20oC). Hint: If the boiling point is below 20oC, then the liquid has already boiled and is a gas. What is the the boiling point trend in terms of the molecular weights of the compounds? At room temperature, the lighter alkanes are gases; the midweight alkanes are liquids; and the heavier alkanes are solids, or tars.
