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.
Salt will melt (become liquid) at 801 degrees Celsius, 1074 degrees Kelvin, 1474 degrees Fahrenheit. It will vaporize at 1465 degrees Celsius, 1738 degrees Kelvin, 2669 degrees Fahrenheit. 801 degree Celsius or 1074 Kelvin It will melt when heated above this temp. It will freeze when cooled below this temp.
