Chlorophyll a melting point
WebMelting points are often used to characterize organic and inorganic crystalline compounds and to ascertain their purity. Pure substances melt at a sharp, highly-defined temperature (very small temperature range of 0.5 – 1 °C) whereas impure, contaminated substances generally exhibit a large melting interval. WebA) is melting arctic snow exposing dark surfaces that heat up and cause further melting B) is a thermostat turning on the furnace as the temperature drops C) are predators eating most of their prey and then declining in numbers D) is a pond becoming more acidic as a result of pollution E) are birds migrating south in response to colder temperatures
