A circuit is a path along which electric current flows. How would changing the battery in a circuit from 9 volts to 1.5 volts most likely affect the circuit? More electric charge would flow in the circuit. Less electric charge would flow in the circuit. The resistance in the circuit would decrease. The resistance in the circuit would increase.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

Need ! asap will mark 10 pts using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit
