D Correct answer
Explanation

Natural gas liquids (NGLs) are separated from methane using absorption processes, cryogenic expansion (cooling to liquefy heavier components), and fractionation towers. Magnetic processes have no application in gas-liquid separation as these methods don't differentiate based on magnetic properties in this context.

Multiple choice

Which of the following are applications of Infrared and Millimeter waves?

  1. Short range communication/ TV remote control
  2. Personal Area Networks
  3. Data communication/Internet
  4. Satellite communication

  1. 1, 2 & 4

  2. 1 & 2

  3. 3 & 4

  4. 1 & 4
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Infrared and Millimeter waves are high frequency, low wavelength waves. They can be used for short range applications only. So, only Remote Control and Personal Area Networks are correct.
