We are constantly surrounded by many types of energy transfers and transformations, showing that energy in a system is conserved
. Which of these statements are true about how energy is conserved through transfers and transformations? Choose the two that apply. A. Energy is conserved when a lamp is turned on because some of the electrical energy is transferred into thermal energy. B. Energy is conserved when thermal energy is transferred from your body to a coat. C. Energy is conserved when some of the chemical energy from burning a candle is transformed into thermal energy, while the rest of the chemical energy is transformed into light energy. D. Energy is conserved when electrical energy from a hair dryer is transferred into thermal energy and then transformed by conduction.
Energy is conserved when some of the chemical energy from burning a candle is transformed into thermal energy, while the rest of the chemical energy is transformed into light energy.
Energy is conserved when thermal energy is transferred from your body to a coat.
Explanation:
The principle of conservation of energy states that energy can neither be created nor destroyed, but can be transformed from one form to another. This can be regarded as the first law of thermodynamics.
In the answer, we see two major kinds of energy transformation around us. The both cases show the conservation of energy in a system.
In the covalent bond, a pair of electrons is shared between two atoms, in this case we have 4 electrons in one atoms and they are shared in pairs, so for these as far apart as possible due to electron-electron repulsion between the electrons of different bonds it must have a TETRAHEDRAL geometry
