The photoelectric effect could not be adequately explained with a wave model of light because. A. the energy of the electrons ejected from a metal varied directly with the intensity. B. the number of electrons ejected from a metal depended upon the intensity.
WebHow Candles Burn. All waxes are essentially hydrocarbons, which means they are largely composed of hydrogen (H) and carbon (C) atoms. When you light a candle, the heat of the flame melts the wax near the wick. This liquid wax is then drawn up the wick by capillary action. The heat of the flame vaporizes the liquid wax (turns it into a hot gas ... WebThe candle wick soaks up hot wax, which burns hot enough in air to excite some electrons of the hot atoms and molecules to higher energy levels. As the electrons drop back down …
