Because the dispersion forces between polythene are greater and stonger becauseit has long chains of ethenes. Whereas, the dispersion forces between ethene arent that great because its just a single monomer, hence ethene is a gas and polyethene a solid

Polyethylene oxide and polyethylene glycol are both polymers made of repeating ethylene glycol units. The main difference between them is their molecular weight. Polyethylene oxide has a lower molecular weight and is a liquid at room temperature, while polyethylene glycol has a higher molecular weight and is a solid or semi-solid at room temperature. Additionally, polyethylene glycol is commonly used in pharmaceuticals and cosmetics, while polyethylene oxide is used in industrial applications.
