What is the difference between a construction manager and a general contractor? Whereas a general contractor’s duties are largely confined to the on-site management of subcontractors, budgets and suppliers, a construction manager provides these services while being involved in the project from the very beginning. What is the difference between a contractor and a construction […]
Can heat energy be converted into potential energy?
Can heat energy be converted into potential energy? If I boil some water on an electric stove, will the heat energy imparted change into potential energy (state changes: water to steam). YES. It does as a result of a sequence of changes to the kinetic and/or potential energy of the heating element, pot, and the […]

How does significant figures relate to accuracy?
How does significant figures relate to accuracy? Accuracy refers to how closely a measured value agrees with the correct value. Precision refers to how closely individual measurements agree with each other. The number of significant figures is the number of digits believed to be correct by the person doing the measuring. What is the meaning […]
How do you find the torque spec of a car?
How do you find the torque spec of a car? Any repair manual specific to your vehicle (Chilton’s, Haynes, Motor, Factory manual, etc.) You can find them at most parts stores, you can check them out at your public library, you can find them on eBay and sometimes on craigslist, and you can download a […]
How does an AC dehumidify?
How does an AC dehumidify? Air Conditioners Benefit from Dehumidifiers Air conditioners aid that process thanks to the liquid refrigerant that facilitates the cooling process. As the refrigerant enters the evaporator coils, it shifts to gaseous form, which pulls heat from nearby warm air and creates condensation to dehumidify it. Where should you place a […]

Overall, a two-stroke engine contains two processes: Compression stroke: The inlet port opens, the air-fuel mixture enters the chamber and the piston moves upwards compressing this mixture. […]
What is the name of the chemical process that causes concrete to harden?
What is the name of the chemical process that causes concrete to harden? hydration What is the chemical reaction in concrete? Portland cement’s chemistry comes to life in the presence of water. Cement and water form a paste that coats each particle of stone and sand—the aggregates. Through a chemical reaction called hydration, the cement […]
Which changes take place when molten metal is poured into a mold?
Which changes take place when molten metal is poured into a mold? Permanent mould casting is a process for producing a large number of castings using a single reusable mould. The casting process simply involves pouring molten metal into a mould where it cools and solidifies. This generates a fast solidification rate which produces a […]
Is potential energy negative or positive?
Is potential energy negative or positive? This is a negative value for two reasons; the force acting between them is attractive, and the zero of potential energy is at infinite separation. This is a negative result if the force between the two charges is attractive (they are opposite) and positive if it is repulsive (the […]
