Which of the following statements is most accurate? a. when liquid water is heated, the molecules move faster. b. when liquid water is heated, the molecules collide more often. c. when liquid water is heated, collisions between molecules are more violent. d. all of the above.

D. All of the above

Explanation:

When liquid water is heated, its molecule get extra kinetic energy and they move faster, when molecules move faster collision between them increases and these collisions are more violent as they move randomly so collision between molecules are more violent and heat is generated Latent heat will also release increases overall heating effect.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

temp rises, and expansion
