<h2>Hello!</h2>

The answer is:

The temperature will be the same, 37°C.

<h2>Why?</h2>

Since from the statemet we know the first temperature, pressure and volumen of a gas, and we need to calculate the new temperature after the pressure and the volume changed, we need to use the Combined Gas Law.

The Combined Gas Law establishes a relationship between the temperature, the pressure and the volume of an ideal gas using Boyle's Law, Gay-Lussac's Law and Charles's Law.

The law establishes the following equation:

\frac{P_{1}V{1}}{T_{1}}=\frac{P_{2}V{2}}{T_{2}}

Where,

P_{1} is the first pressure.

V_{1} is the first volume.

T_{1} is the first temperature.

P_{2} is the second pressure.

V_{2} is the second volume.

T_{2} is the second temperature.

Then, we are given the following information:

V_{1}=200mL\\P_{1}=4atm\\T_{1}=37\°C\\V_{2}=400mL\\P_{2}=2atm

So, isolating the new temperature and substituting the given information, we have:

\frac{P_{1}V{1}}{T_{1}}=\frac{P_{2}V{2}}{T_{2}}\\\\T_{2}=P_{2}V{2}*\frac{T_{1}}{P_{1}V_{1}} \\\\T_{2}=2atm*400mL*\frac{37\°C}{4atm*200mL}=37\°C

Hence, we have that the temperature will not change because both pressure and volume decreased and increased proportionally, creating the same relationship that we had before the experiment started.

The temperature will be the same, 37°C

Have a nice day!

Sort each of the following events based on whether the solubility of the indicated gas will increase, decrease, or stay the same
STatiana [176]

The answers are: 1) decrease 2) increase 3) decrease 4) increase 5) increase

<h3>FURTHER EXPLANATION</h3>

The following factors affect the solubility of gases in liquids:

1. Temperature - inverse relationship

<em>As the temperature is increased, the gas particles gain energy and start to move faster. This enables them to escape the liquid leading to decrease in the solubility of the gas. </em>

2. Partial Pressure of gas - direct relationship

<em>According to Henry's Law, for a given temperature, the solubility of the gas and the partial pressure of the gas above the liquid are proportional. With the application of pressure on the gas above the liquid, the gas particles are forced to move into the solvent.</em>

<em />

1. Temperature is increased - gas solubility decreases (Factor 1)

2. Partial pressure of an anesthetic gas is increased - gas solubility increases  (Factor 2)

3. O2: temperature of a body of water rises - gas solubility decreases (Factor 1)

4. Pressure of a gas over a solvent is increased - gas solubility increases (Factor 2)

5. Air in blood: a diver descends 10 m and the pressure increase by 1 atm - gas solubility increases (Factor 2)

<em>As the diver goes deeper, the pressure increases and more gases dissolve in the diver's blood. As the diver ascends, he or she must do so slowly to ensure that this large amount of gas is removed from the blood gradually otherwise, the diver might suffer from decompression sickness.</em>
