Answer:

Lower.

Explanation:

When you lower the pressure of water, it will usually decrease the boiling point. So, the higher you are on Earth, the lower the boiling point of H2O becomes.

<h3><u>Answer;</u></h3>

exceeds evaporation over land

Precipitation<u> exceeds evaporation over land </u>

<h3><u>Explanation;</u></h3>
  • <em><u>In order to maintain earths water balance, evaporation exceeds precipitation over oceans but precipitation exceeds evaporation over land.</u></em>
  • Water evaporates into the atmosphere from the ocean and to a much lesser extent from the continents. Winds transport this moisture-laden air, often great distances, until conditions cause the moisture to condense into clouds and to precipitate and fall.
  • Most precipitation originates by evaporation from the oceans. Over time, water evaporated from the oceans is replenished by inflow of freshwater from rivers and streams.

Which of the following options would be the best for dissolving PbBr2(s)?
Nezavi [6.7K]

Answer:

2) Add a solution of NaBr

Explanation:

Lead (II) bromide is an inorganic powdery substance that has a solubility in water of 0.973 g/100 mL at 20°C. It is insoluble in alcohol but is soluble in alkali, ammonia, NaBr, and KBr

PbBr₂ is slightly soluble in ammonia, and it reacts with NaOH to produce Pb(OH)₂ and NaBr

Therefore, the best solution for dissolving PbBr₂(s) is NaBr

Method A: Does not transfer heat through solids and requires a medium for heat transfer Method B: Requires a material medium and
Paha777 [63]

Method A is Convection

Method B is Conduction

Explanation:

From the problem, we can infer that method A is convection and method B is conduction.

Conduction, convection and radiation are the three main methods of heat transfer.

  • Conduction and convection requires material medium to propagate.
  • Radiation occurs in the absence of a material medium.
  • Conduction mostly occurs in solid. Here, heat is transferred from one hot end to the cold end of the solid. The vibration of the particles in the hot end causes the transfer of kinetic energy to the cold end until thermal equilibrium is reached.
  • In convection, heat is primarily transferred in fluids as a result of density differences. Convection involves the motion of the materials of the medium. Hot air is light and it rises whereas cold air is dense and it sinks.
