Question: Characteristics of styrofoam cup before placing it in water
Subject: Science
Styrofoam cups are utensils made of polystyrene foam that are used for drinking purposes. The physical properties of the cups before placing in water are firm and hard in shape.
What are physical characteristics?Physical characteristics are the properties that are not manifested by the chemical reactions and include the measurable and visible state, including conductivity, hardness, solubility, shape, malleability, melting points, color, etc.
Styrofoam cups are thermoplastic which allows them to remain solid at RT and liquid at the boiling point. They can be arranged and molded into various shapes and sizes according to the need.
The cups are stiffer and stronger before they are placed in water, but after they are placed in water they lose their firmness and become soft.
Therefore, the styrofoam cups are solids and a little firm before placing in water.
