What is urea formaldehyde foam insulation? Urea formaldehyde foam insulation is injected as a mixture of urea formaldehyde resin, an acidic foaming agent, and a propellant, such as air. It was commonly used in existing houses by injecting the foam into areas, such as behind walls, where it was impractical to provide conventional insulation. Is […]
What are the two basic methods of arc shielding?
What are the two basic methods of arc shielding? What are the two basic methods of arc shielding? (1) Shielding gas, such as argon and helium; and (2) flux, which covers the welding operation and protects the molten pool from the atmosphere. Why is the shielded metal arc welding process difficult to automate? Why is […]
What is the relationship between voltage and temperature?
What is the relationship between voltage and temperature? Voltage is directly proportional to resistant (V=IR) and resistance increases with temperature due to increased vibrations of the molecules inside the conductor. Therefore voltage increases as temperature increases. What is the relationship between voltage and resistance? Ohm’s law defines the relationship between the voltage, current, and resistance […]

What do chemical engineers contribute to society?
What do chemical engineers contribute to society? Chemical engineers have made so many important contributions to society, in such a short span of history, that it is hard to visualize modern life without the large-scale production of antibiotics and other drugs, fertilizers, agricultural chemicals, physiological-compatible polymers for biomedical devices, high- … What industries do chemical […]
Why do some appliances have 2-prong plugs?
Why do some appliances have 2-prong plugs? Many appliances in the USA and elsewhere have two-prong plugs because they are “double insulated.” The third prong is for ground fault protection except where outlets have been designed with protective shutters on the current-carrying slots that are opened by the ground prong. What is a 2-prong outlet […]

What is differential input voltage?
What is differential input voltage? The differential input voltage is the maximum voltage that can be supplied to the +Input (Non-inverting input) and -Input (Inverting input) pins without causing damage or degrading IC characteristics. Why is differential amplifier needed? Differential amplifiers are used mainly to suppress noise. Noise is generated in the wires and cables, […]
Why is it important to determine the impacts of technology on society?
Why is it important to determine the impacts of technology on society? Technology affects the way individuals communicate, learn, and think. It helps society and determines how people interact with each other on a daily basis. Technology plays an important role in society today. It has positive and negative effects on the world and it […]
