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.
As the temperature is increased, the viscosity of the softened polymer will decrease until it reaches a temperature near 110 C (230 F). This is the temperature at which the baseline of the scan starts to rise rapidly, and the gap between 75 C and 110 C represents the window of opportunity for blowing the bottle.
