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.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
