Brazing welding is a process of joining two metal pieces using a filler metal that melts at a lower temperature than the base metal.

• Brazing welding is commonly used in HVAC systems, plumbing, and automotive industries.

• It requires a torch or furnace to heat the base metal and the filler metal.

• The filler metal is then melted and flows into the joint, creating a strong bond.

• Brazing welding is different from soldering as it requires higher temperatures and creates a stronger join...read more

pH measures acidity/basicity, conductivity measures electrical conductivity, cooking types refer to methods of preparing food.

• pH is measured on a scale of 0-14, with 7 being neutral, below 7 acidic and above 7 basic

• Conductivity is measured in siemens per meter (S/m) and is used to determine the concentration of ions in a solution

• Cooking types include baking, frying, grilling, boiling, steaming, etc.

• Each cooking type has its own unique characteristics and is used for different...read more

The laws of thermodynamics are fundamental principles that govern energy and its transformations in the universe.

• The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted.

• The second law of thermodynamics states that the entropy of an isolated system will always increase over time.

• The third law of thermodynamics states that as temperature approaches absolute zero, the entropy of a system approaches a minimum value.

• Examples...read more
