The visual or mathematical representation of an object system or concept is known as a model. Hope this helps and mark as brainliest!
In the given examples, Cl2 and CCl4 are non-polar and held by covalent bonds. HI and H2O are polar molecules and held by ionic bonds.
Since covalent bonds are weaker than ionic bonds, Cl2 or CCl4 must have the lowest melting points. Among the two, Cl2 has a lower molecular mass than CCl4, hence Cl2 must have the lowest melting point.
Ans A) Cl2
humidity can be measured by the simplest hygrometer, called a sling psychrometer. It is composed of two thermometers placed together with a handle set to a chain. One of the thermometers is just like any other thermometer. Erstwhile the other one has a cloth wick wrapped over its bulb and is called a wet-bulb thermometer.
Have a great day!
