Question

Please help me *cries* PLEASE

X and Y are two imaginary substances. The molecules of substance X have very powerful electric forces between them. The molecules of substance Y have almost no electrical forces linking them. Which boils at a higher temperature?
1. X
2. it’s impossible to know
3. Y

Answer 1

Answer: X

Reason

Boiling is defined to be the transition from liquid to gas. For example, boiling water to get water vapor (aka steam).

When the substance is a liquid, the molecular bonds hold it loosely together so there's some kind of cohesion going on (and it's not just a loose collection of bouncy balls for instance). At a solid phase, the connections are much tighter with less movement.

If the substance has a powerful electrical force holding the atoms together, then it's going to take a lot more energy to heat it up to get the liquid to boil to a gas. In contrast, a substance with weak to no electrical forces linking the atoms, will be much easier to boil. Hence the boiling point is much lower. The atoms can escape easier to form a gas.

This is why substance X is tougher to boil and has a higher boiling point.

Answer 2

Substance X, having powerful electric forces between molecules, boils at a higher temperature than substance Y, which has almost no such forces.

Step-by-step explanation:

The question involves understanding the boiling points of substances X and Y based on the strength of their intermolecular forces. In general, substances with strong intermolecular interactions require more energy to transition from a liquid to a gas, which means they have higher boiling points. Since substance X has very powerful electric forces between its molecules, it would require more energy to break these forces compared to substance Y, which has almost no electrical forces linking them. Thus, substance X would boil at a higher temperature than substance Y.
