2.Chemical energy is converted to mechanical energy.
3. Chemical energy is converted to heat energy.
4. Chemical energy is converted to mechanical and kinetic energy.
the correct answer is 1. Chemical energy is converted to mechanical and heat energy.
When the boy eats apple, the chemical energy of the apple first converted in the heat energy in the process of digestion, which maintains our body temperature, than the body of the boy converts the heat energy into mechanical energy.
Therefore the correct option is 1.
Answer:
Chemical energy is converted to mechanical and heat energy.
Explanation:
Answer: Both of the compounds contain primary bonding; however, the bonding is of different types. Magnesium chloride (MgCl₂) contains ionic bonds, which are stronger and involve the complete transfer of electrons. Meanwhile, ethane (C₂H₆) also bonds by electron transfer but the electrons are not completely transferred from one atom to another. Instead, they are shared, forming what is known as a covalent bond.
Kinetic energy and temperature decrease; thermal energy increases.
B.
Kinetic energy, temperature, and thermal energy decrease.
C.
Kinetic energy and temperature increase; thermal energy decreases.
D.
Kinetic energy, temperature, and thermal energy increase.
i think its D, but im not sure.
Possible answers:
oceans/seas/lakes/rivers
atmosphere/sky
Explanation:
Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.
