What does the ideal gas law allow a scientist to calculate that the other gas laws do not?

The ideal gas law allows a scientist to calculate the number of moles that the other gas laws do not. The ideal gas law is given as

P V = n RT

rearranging the equation by dividing both side by "RT", we get

PV/(RT) = nRT/(RT)

n = PV/(RT)

inserting the values of pressure, volume and temperature, we get number of moles.

<u>The ideal gas law allows the scientists to calculate the number of moles of the gas whereas other gas laws deal with the temperature, pressure and volume of the gas only.</u>

Further Explanation:

The ideal gas law for an ideal gas establishes the relation between the pressure, volume, temperature and the number of moles of a gas. According to the ideal gas law, the product of the pressure and volume of the gas is directly proportional to the product of the number of moles and the temperature of the gas.

The ideal gas law can be represented mathematically as.

${PV}$ ∞ ${nT}$

Remove the proportionality constant.

$\boxed{\text{}PV=nRT}$

Here, $P$ is the pressure of gas, $V$ is the volume of the gas, is the number of moles, $R$ is the gas constant and $T$ is the temperature of the gas.

The other gas laws are the Boyle’s Law and the Charles’ Law. The Boyle’s Law states that at constant temperature, the pressure of a gas is inversely proportional to the volume of the gas.

On the other hand, the Charles’ Law states that at constant pressure, the volume of a gas is directly proportional to the temperature of the gas.

It shows that the other gas laws only establish the relation between the pressure, temperature and the volume of the gas but do not deal with the number of the moles of gas. <u>The number of moles can only be known from the ideal gas law.</u>

slega [8]

The highest point of the wheel is the position of the wheel when its potential energy is greatest.

<h3>At what position of the wheel potential energy is greatest?</h3>

The position of the wheel when its potential energy is greatest when it is at the highest point because potential energy depends on the height of an object. If the object is at more height then it has more potential energy and vice versa.

So we can conclude that the highest point of the wheel is the position of the wheel when its potential energy is greatest.

Answer: B

Longitudinal wave

Explanation:

Transverse waves have crests and troughs

Longitudinal waves have compressions and rarefactions. A compression is where the density of the wave medium is highest. While a rarefaction is where the density of the wave medium is lowest.

Since sound wave is a longitudinal wave. And longitudinal wave exists apart from sound, we can therefore conclude that it's a longitudinal wave in spring.

Answer:

The correct answer is d. tension pneumothorax.

Explanation:

The increasing build-up of air that is in the pleural space is what we call the tension pneumothorax and this happens due to the lung laceration that lets the air to flee inside the pleural space but it does not return.
