The tumbleweed dispersal strategies are unusual among plants; most species disperse their seeds by other mechanisms. Many tumbleweeds (though by no means all) are ruderal species, opportunistic agricultural weeds. Tumbleweeds have been recorded in the following plant families:
The most obvious is temperature. If the air temperature is above 32Â°F snow and ice will start to melt, at or below 32Â° and it will remain frozen. Think about a popsicleâ¦ inside the freezer it stays frozen, outside it starts to melt. The amount of sunshine plays a big factor.
Kelvin is degrees in Celsius+273 degrees kelvin so if ice melts at 100 C, then... 100+273=373 degrees kelvin is ice's melting point Supplement. All the above math is good. â¦ BUT ice down here in New Zealand melts at 0oC, so that would be 273oK. [But it would be certain that ice would very soon melt at 100oC, the boiling point of water.]. 2 people found this useful.
