You are doing a peer review of a science experiment. The paper claims that an increase of pressure requires a greater addition o

f thermal energy to change a liquid to a gas. Why is this true?

This is true because as thermal energy increases, molecules move faster and liquids are turned into gas.

States of matter is determined by the amount of energy possessed by the particles. Particles of a solid has the least amount of energy, liquid particles have more energy than solid particles while gas particles possess the highest amount of energy.

To increase the pressure of a substance, greater thermal energy is added to the substance by heating it up. This heat causes the molecules of the liquid to become more energetic and move faster .

As this occurs, intermolecular forces between the substance is broken as the liquid is converted to gas. The pressure. The energetic gas particles collide faster with the walls of the container thereby increasing the pressure.

The presence of Catholicism in Australia in the late 1700s could be BEST explained by the increasing presence of A) Irish convic
defon

Answer:

Irish convicts

Explanation:

European explorers were familiar with Australia since the 1600s. However, they stepped their foot on infertile and dessert parts of the continent, so they showed no interest for this new land. Upon finding fertile land in eastern parts of the continent,  in the 1700s, James Cook claimed it a British land.  

Britain has just lost its colonies in America, so they decided to send men to this new land. However, they considered it infertile, lacking in resources and hard to live on, so they sent convicts, in, what will be known as the First Fleet, in 1788.  

Thus first contingent of ships carried around 1500 convicts, mostly Irish, with more than 100 000 convicts in the following years.

With them, Catholicism arrived in Australia, and later spread throughout the continent.

Yield for this reaction?<br> Reaction: N2(g) + 3 H2(g) → 2 NH3 (g)
andriy [413]

Answer:

Yes, yield.

Explanation:

N2(g) + 3 H2(g) → 2 NH3 (g) balanced equation

First, find limiting reactant:  

Moles H2 = 1.83 g x 1 mole/2 g = 0.915 moles H2

Moles N2 = 9.84 g N2 x 1 mole/28 g = 0.351 moles N2

The mole ratio of H2: N2 is 3:1, so H2 is limiting (0.915 is less than 3 x 0.351)

Theoretical yield of NH3 = 0.915 mol H2 x 2 mol NH3/3 mol H2 = 0.61 moles NH3
