This process involves multiple harmful effects on the local ecosystem and communities. Thermal pollution is best known as sudden increases or decreases in the temperature of water bodies like oceans, seas, rivers, lakes, streams, etc. Usually, the industries use water for cooling purposes for machinery or other production processes.

Heat treatment deformation reasons and prevention methods. 1, the cause of heat treatment deformation. Steel may be deformed or even cracked during the heating and cooling process of heat treatment because of the existence of quenching stress. Quenching stress is divided into thermal stress and tissue stress.

Cause and Effect Analysis is a technique that helps you identify all the likely causes of a problem. This means that you can find and fix the main cause, first time around, without the problem running on and on. The diagrams you create with this type of analysis are sometimes known as fishbone diagrams, because they look like the skeleton of a fish.

Well before kids can even understand the concept, parents start talking to them in terms of cause and effect. We say things like, "Once you eat all of your food, you can have some dessert," and "We need to brush your teeth or they'll get rotten and you'll get cavities."These comments help them start learning that for every cause, there is a related effect.
