D. freezing, deposition, and condensation

Explanation:

In order to understand, let's see the definition of these changes of state:

- freezing: freezing occurs when a substance changes from liquid state to solid state

- deposition: deposition occurs when a substance changes from gas state to solid state, without passing through the liquid state

- condensation: this process occurs when a substance changes from gas state to liquid state

In all the three processes listed above, energy is released from the substance, which in fact loses energy. In fact:

- in a liquid, the particles have more energy than in a solid (because in liquid they can move, while in solid they can only vibrate), so during freezing, since a liquid turns into a solid, it releases energy to the surrounding

- in a gas, the particles have more energy than in a liquid (because in a gas they can move faster than in a liquid), so during condensation, since a gas turns into a liquid, energy is released to the surrounding

- in deposition, the particles change from the gas state (where they move faster) to a solid state (where they are not free to move), so they lose energy as well.

The ball of a ballpoint pen is 0.5 mm in diameter and has an ASTM grain size of 12. How many grainsare there in the ball

Alina [70]

Answer:

the number of grains in the ball is 274,848

Explanation:

Given that;

diameter = 0.5 mm

so radius r = 0.25 mm

first we determine the volume of the ball using the following equation;

V = 4/3×πr³

we substitute

V = 4/3×π(0.25)³

V = 0.06544 mm³

Now form table 1.1 "Grain sizes" a metal with grain size number of 12 has about 4,200,000 grains/mm³

so;

Number of grains N = 0.06544 × 4,200,000

N = 274,848 grains

Therefore, the number of grains in the ball is 274,848
