Sorry but it depends on the gas in question and it's temperature of condensing /boiling point if this it 0° it will turn liquid
Answer:
Correct option is D)
Explanation:
Crystallization is the process that is used to separate a pure solid in the form of its crystals from a solution.
Copper sulphate, salt, and potash alum can be purified by this method. In this process, the solution of the substance is heated and then cooled to form crystals.
Answer:
A base.
Explanation:
Basic solutions give OH- ions.
Answer:
C. Speed
Explanation:
Density differences in different materials are able to change the speed of a wave.
- Wave speed is dependent on the frequency and wavelength of a wave.
- As a wave travels from one medium to another, the speed of the wave changes.
- Speed of a wave is medium dependent.
- The denser a medium, the slower the speed of waves will be be.
- A less dense medium will have waves traveling through faster.
Supercooling<span>, a state where liquids do not solidify even below their normal freezing point. Means sometimes we have liquid water below 0 degree C.</span>
