What current is needed in a 5-turn, 10-cm-diameter coil to cancel the earths magnetic field at the center of the coil?
Chapter 17: Phases and Phase Changes An ideal gas is one that is dilute enough, and far away enough from condensing, that the interactions between molecules can be ignored If the volume of an ideal gas is held constant, we can find that the pressure increases with temperature o P = (constant)T If the volume and temperature are kept constant, but more gas is added, the pressure will increase o P = (constant)N If the temperature is constant and the volume decreases, the pressure increases o P = (constant) / V Combining all of the above equations, we create the following equation o P = k (NT/V) o K = the Boltzmann constant = 1.38 x 10^(23) J/K o PV=NkT
