Answer:
D. The kinetic energy is greater after a substance changes from a
solid to a liquid
Explanation:
During a phase change from solid to liquid, the particles making up the mobile becomes more mobile and as a result there is an increase in kinetic energy of the system.
- Kinetic energy is the energy accrued due to the motion of a body.
- In a melting process where solids turn to liquid, there is an increase in kinetic energy.
- When randomness of a system increase, kinetic energy also increases.
- From liquid to gas and gas to plasma increases kinetic energy.
- In the other way round, the kinetic energy reduces.
Answer:
A
Explanation:
an element contains only one kind of particle
Answer: During the day, a typical greenhouse will trap Infrared photons from the sun, which allows the plants inside to stay warm at night. ... The much needed sunlight will still come through but the extra layer of protection will keep your plants safe at night
Explanation: Hope that helps :)
Hello,
In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.
Hope this helps!!!! Happy Holidays!!!! (:
