Question

what is the role of thermal cracking for preventing in preventing enviornmental pollution​

Answer 1

Answer:

⭐5.5.2.1 Thermal Cracking in Grain Boundaries and Within Grains

5.5.2.1 Thermal Cracking in Grain Boundaries and Within GrainsThere are two types of thermal cracking (or damage) in rocks. One is called intercrystalline or intergranular cracking, meaning that cracking happens in grain boundaries. The other is named intracrystalline or intragranular cracking, that is, cracking occurs within a grain. The experimental investigation showed that for the Remiremont granite, the intergranular cracks predominated over the intragranular cracks, probably because its intragranular crack lengths were limited due to its small grain size [9]. For Senones granite (with large crystals) its intergranular cracking was also greater than its intragranular cracking when the temperature was below 500°C. But from 500 to 600°C the intragranular cracking of the Senones granite largely increased and was much greater than its intergranular cracking.

Answer 2

Answer:

The primary effects of thermal cracking pollution are direct thermal shock, changes in dissolved oxygen, and the redistribution of organisms in the local community.
