D.
This happens because in warmer temperatures, the atoms are more active. This increases the pressure because each atom uses up more space as they become more active.
Answer:
True
Explanation:
It only becomes a law when someone has proved it, or else it's just a theory.
I don't know what the answer to your first question is. All of my teachers have only called it the equilibrium point. However for your second question, a hydrogen bond is a special type of dipole-dipole attraction. Only oxygen, nitrogen, and fluorine are able to make them when bonded with hydrogen. Hydrogen bonding is what makes water have such a high boiling point considering how light the molecule is.<span />
Kepler did not study the speed of the planets, rather, he studied how the planets move in the solar system. He proposed three laws. As a summary, he described that the planets move around the sun in the shape of an ellipse (orbit), and the Sun being one of the foci. Then, he proposed the period for the planet to complete one revolution around the Sun.
On the other hand, Newton studied the forces acting on the planet (or any object in space) that explain how the planets move around the solar system as described by Kepler. Also, Kepler's observations only apply to planets and not the moons or satellites. Thus, Kepler only made laws from observations, while Newton based it from underlying principles that led him to mathematical equations such as the law of universal gravitation.
