Lithium is used to build computer batteries, whereas iron is used in industry to construct buildings and bridges.

<h3>What are metals?</h3>

In engineering, metals are characterized to have electrical conductivity and other properties (e.g., ductility, reflectivity, etc).

For example, Lithium can be defined as soft metal (alkali metal) that is suitable to store electrical energy.

In conclusion, Lithium is used to build computer batteries, whereas iron is used in industry to construct buildings and bridges.

What happens to the partial pressure of oxygen in a sample of air if the temperature is increased? It increases. It decreases. I
Leno4ka [110]

The partial pressure of oxygen in a sample of air increases if the temperature is increased.

Answer: Option 1

<u>Explanation: </u>

According to Guy-Lussac's law, at constant volume, pressure exhibited by the gas molecules will be directly proportional to the temperature of the gas molecules. It is also known that pressure of mixture of gas molecules is the sum of partial pressure of each gas molecule in the mixture.

If the temperature increases, the partial pressure and the pressure of the mixture of gas also tend to increase. As it can be seen that at higher altitudes, the low temperature leads to the decrease in oxygen's partial pressure in the air.

So, it can also be concluded that temperature increases the oxygen's partial pressure in air increases.

If a sample of oxygen gas originally at from 171.4 K has its temperature increased to 288.4 K and
julia-pushkina [17]

Answer:

V₂ = 0.95 L

Explanation:

Given data:

Initial temperature of gas = 171.4 K

Final temperature of gas = 288.4 K

Final volume = 1.6 L

Initial volume = ?

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₁ = V₂T₁ /T₂

V₂ = 1.6 L × 171.4 K / 288.4 k

V₂ = 274.24 L.K / 288.4 K

V₂ = 0.95 L
