5. As a sample of matter is heated, its particles *O A are unaffected
O B. move more quickly
O C. move more slowly
D. stop moving

Answers

Answer:

B. move more quickly

Explanation:

As a sample of matter is heated, we know that the particles begins to move more quickly.

This is because the temperature of a substance is directly proportional to the average kinetic energy of a system.

  • As the temperature increases, the body gains more kinetic energy
  • This is translated to the particles of the medium.
  • Then they begin to move quickly and very fast enough.

Final answer:

Upon heating a sample of matter, the particles tend to move more quickly. This is because the increase in temperature boosts the kinetic energy of the particles, thereby making them move faster.

Explanation:

When a sample of matter is heated, it causes the particles of the matter to move more quickly. This phenomenon is due to the increase in temperature, which leads to an increase in the kinetic energy of the particles. Kinetic energy refers to the energy that an object possesses due to its motion. Hence, as heat supplies energy, it causes atoms and molecules in a matter to move faster. As a result, solids expand and liquids and gases become less dense as their particles spread out to absorb the heat.

Ammonia, methane, and phosphorus trihydride are three different compounds with three different boiling points. Rank their boiling points in order from lowest to highest.A. CH4< NH3 < PH3
B. NH3 < PH3< CH4
C. CH4 < PH3 < NH3
D. NH3 < CH4< PH3
E. PH3< NH3 < CH4

Answers

Answer:

B. NH3 < PH3< CH4

Explanation:

Hello,

In this case, taking into account that the boiling point of ammonia, methane and phosphorous trihydrate are -33.34 °C, -161.5 °C  and -87.7 °C, clearly, methane has the lowest boiling point (most negative) and ammonia the greatest boiling point (least negative), therefore, ranking is:

B. NH3 < PH3< CH4

In the United States, volume of irrigation water is usually expressed in acre-feet. One acre-foot is a volume of water sufficient to cover 1 acre of land to a depth of 1 ft (640 acres = 1 mi2, 1 mi = 5280 ft). The principal lake in the California Water Project is Lake Oroville, whose water storage capacity is listed as 3.54 x 106 acre-feet. Express the volume of Lake Oroville in (a) cubic feet, (b) cubic meters, and (c) US gallons.

Answers

Answer:

a) V = 1.542 E11 ft³

b) V = 4367011968 m³

c) V = 1.1535 E12 us gal

Explanation:

Acre surface is defined as 66 by 660 feet at a depth of one foot:

⇒ Vacre-foot = 66ft*660ft*1ft = 43560 ft³

lake:

a)  V = 3.54 E6 acre-feet * ( 43560 ft³ / acre-foot ) = 1.542 E11 ft³

b) V = 1.542 E11 ft³ * ( 0.02832m³ / ft³ ) = 4367011968 m³

c) V = 1.542 E11 ft³ * ( 7.48052 us gal/ft³ ) = 1.1535 E12 us gal

1. Potassium (K) has an atomic mass of 39.0983 amu and only two naturally-occurring isotopes. The K-41 isotope (40.9618 amu) has a natural abundance of 6.7302%. What is the mass (in amu) of the other isotope

Answers

Answer:

38.96383282 amu

Explanation:

39.0983 = (40.9618 * 0.067302) + ( ? * (1-0.067302)

39.0983 = 2.756811064 + ( ? * 0.932698)

subtract 2.756811064 from both sides

36.34148894 = ( ? * 0.932698)

divide both sides by 0.932698

? = 38.96383282 amu

Answer:

38.96383282 amu

Explanation:

39.0983 = (40.9618  0.067302) + ( ?  (1-0.067302)

39.0983 = 2.756811064 + ( ?  0.932698)

subtract 2.756811064 from both sides

36.34148894 = ( ?  0.932698)

divide both sides by 0.932698

? = 38.96383282 amu
