<h3>What is hexadecimal system?</h3>

Hexadecimal is an easy route for addressing twofold. It is vital to take note of that PCs don't utilize hexadecimal - it is utilized by people to abbreviate parallel to an all the more effectively reasonable structure. Hexadecimal Number System is generally utilized in Computer programming and Microprocessors. It is likewise useful to portray colors on pages. Every one of the three essential tones is addressed by two hexadecimal digits to make 255 potential qualities, hence bringing about in excess of 16 million potential tones. The primary benefit of utilizing Hexadecimal numbers is that it utilizes less memory to store more numbers, for instance it stores 256 numbers in two digits while decimal number stores 100 numbers in two digits. This number framework is likewise used to address Computer memory addresses.

ii. If the pressure after landing was 1.0 atm, what was the volume of the passenger's collapsed water bottle? (Assume the bottle
Anon25 [30]

Using the ideal gas equation and Gay Lussac's law, the volume of the passenger's collapsed bottle after landing is 0.0075 L.

<h3>What is ideal gas equation?</h3>

The ideal gas equation shows the relationship between temperature, pressure, volume and number of moles.

The volume of the passenger's collapsed bottle after landing is 0.0075 L.

Given that;

PV = nRT

  • P = gas pressure
  • V = volume of gas
  • n = number of moles of gas
  • R = molar gas constant
  • T = temperature

n = PV/RT

Hence:

P = 0.75 atm;

V = 0.5 L;

T = 295 K;

R = 0.082 atmL/K.mol

n = 0.75 * 0.5 / 0.082 * 295

n = 0.015 moles

If the pressure after landing was 1.0 atm;

V1n1 = V2n2

V2= V1n1/n2

V2 = 0.5 L *  0.015 moles/ 1 mole

V2 = 0.0075 L

The volume of the passenger's collapsed bottle after landing is 0.0075 L.

Missing parts;

A passenger on an airplane finished a 0.5 L bottle of water during the flight

and replaced the lid. The cabin pressure and temperature were maintained at

0.75 atm and 295 K during the flight. After landing, he noticed his empty water

bottle had collapsed. (12 points)
