The metal copper has a specific heat of 0.386 J/g⋅K. How much heat is needed to raise the temperature of 1 kg (1,000 g, or 2.2 pounds) of copper from 0 °C to 100 °C? Q = (m)(C)(ΔT) = (1,000 g)(0.386 J/g⋅K)(100 K) = 38,600 J = 38.6 kJ. ...
Many states have created "insurers of last resort" to provide policies for people who can't get them anywhere else. An independent agent can help you find your state's last-resort insurer, if it has one. Make your home more climate-resilient ...
The most common method of making magnets today involves placing metal in a magnetic field. CRStocker/Shutterstock To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needl...
