1.sublimation
example: sand and camphor
2.centrifugation

The Big Bang theory is one of the ones used most frequently nowadays to describe how the cosmos came into being.
<h3>What does big bang theory state?</h3>
According to this theory, the universe formed 13.8 billion years ago as a result of the primordial atom, a single particle, exploding and generating an unprecedented cosmic disaster. The universe is always expanding, according to the same theory.
The key supporting data for the big bang theory are:
The galaxies to getting further and distant from us. This distance is taken at high speeds. In other words, the distance between galaxies is inversely correlated with their spacing velocity. Our perception of galaxy dysthanization occurs because the universe is continually expanding, according to this data, which is known as the "Hubble Law," and this hypothesis also explains that The cosmos has already been unified.
According to the big bang theory, the cosmos was extremely hot at the time of its creation; if this is accurate, we should find some proof of this warmth. Radio astronomers discovered this proof when they noticed that microwaves with a temperature of 2,725 degrees Kelvin included cosmic background radiation. This radiation is perhaps proof of the universe's high temperature.
Last but not least, the Big Bang most likely contributed to the abundance of hydrogen and helium elements.

For example:
5Cl₂ + I₂ + 12NaOH = 10NaCl + 2NaIO₃ + 6H₂O
Na₂S₂O₃ + 4I₂ + 10NaOH = 8NaI + 2Na₂SO₄ + 5H₂O
Answer:
A thermometer has a glass tube sealed at both ends and is partly filled with a liquid like mercury or alcohol. As the temperature around the thermometer's bulb heats up, the liquid rises in the glass tube. ... When it is hot, the liquid inside the thermometer will expand and rise in the tube
