A box is initially at the top of a slide, storing 80 J of gravitational energy. The isolated system includes the box, slide and earth.
As the box slides down the frictionless slide, what happens to the total energy of the system?

1-the isolates system stores slightly less than 80 J of total energy, and it is converted to a different form of energy

2- The isolated system stores 80 J of total energy, but it is converted to a different foe of energy

3- The total energy of the system increases to more than 80 J as it gains other forms of energy

4- The total energy of isolated system decreases to 0 once the box reaches the bottom of the slide

la respuesta es si te gusta hacer lo que siempre haces cuando nunca ves a alguien en el espejo porque sabes que no siempre están ahí.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
