Form of complex numbers a + bi Real and imaginary parts of z = a + bi Re(z) = a, Im(z) = b When two complex numbers are equal, what is true Their real parts are equal and their imaginary parts are equal i² -1 i³ -i i⁴ 1 Determinant for two real roots (distinct roots) b² - 4ac > 0 Determinant for one real root (repeated roots) b² - 4ac = 0 Determinant for no real roots (two distinct complex roots) b² - 4ac < 0 Co...

1. A decrease in the temperature of a gas sample in a closed container will always result in an increase in the: A. value of the PV / (RT) ratio. kinetic energy of individual gas molecules. C. gas pressure on the container. D. attraction between gas molecules. Correct Explanation: D. Since the temperature of a gas is proportional to the average kinetic energy of its molecules, decreasing the temperature will result in a decrease in kinetic energy. This decrease in kinetic energy will ...
