Which statement explains how heat causes materials to expand?
a. Higher temperatures increase the kinetic energy of the particles, which causes the particles to move more and take up more space.
b. Higher temperatures increase the kinetics energy of the particles, which causes the particles to pack closely together.
c. Lower temperatures decrease the kinetic energy of the particles, which causes the particles to move less and take up more space.
d. Lower temperatures increase the kinetic energy of the particles, which causes the particles to spread out.

This 100% correct i promise
1. Higher temperatures increase the kinetic energy of the particles, which causes the particles to move more and take up more space.
2. synthetic material
3. Conductors allow for more electric current than insulators
4. It blocks or decreases the electric current, changing the energy into the light it produces.
5. gold
6. tiny holes in the fabric
7. Consumers would not need to make trade-offs about up-front costs.
8. It would prevent an oil pipe from snapping and leaking if a rig were to sink.
9. increase the thickness of the wall material
10. ion
11. road
12. structural
13. suspension
There you go! have an amazing day :)
