P*V = n*R*T where P = pressure V = volume n = number of moles R = the universal gas constant T = temperature in degrees Kelvin This equation is known as the ideal gas law, and it can be used to predict the behavior of many gases at relatively low

What might happen to white peppered moths if the trees they live on become covers in soot

A ten-loop coil having an area of 0.23 m2 and a very large resistance is in a 0.047-T uniform magnetic field oriented so that the maximum flux goes through the coil. The coil is then rotated so that the flux through it goes to zero in 0.34 s.
