Answer:
The water takes longer, because it is the better insulator here.
Explanation:
Conductors and insulators work similarly in "reverse".
If something is a good heat conductor, then it's good at both absorbing heat energy and giving it away. Insulators are good at resisting temperature changes, but also take longer to cool down once they are heated up.
So because copper is the better conductor here, it will cool faster than the water at the same temperature.
Explanation :
<em>Law of conservation says that the total momentum of any closed and isolated system cannot </em><u><em>change</em></u><em>. </em>
Law of conservation of momentum implies that initial momentum is equal to the final momentum. This law is true for an isolated system. Isolated system means net external force acting on it is equal to zero.
Momentum is the product of mass and velocity with which an object is moving.
i.e. p = m v
Answer:
Explanation:
One mole of a substance contains the same amount of representative particles. These particles can be atoms, molecules, ions, or formula units. In this case, the particles are atoms of titanium.
Regardless of the particles, there will always be <u>6.02*10²³</u> (also known as Avogadro's Number) particles in one mole of a substance.
Therefore, the best answer for 1 mole of titanium is D. 6.02*10²³ atoms.
