Indicate whether each statement is true or false: (a) Elastomers are rubbery solids. (b) Thermosets cannot be reshaped. (c) Thermoplastic polymers can be recycled.

Verified step by step guidance

Understand the definition of elastomers: Elastomers are a type of polymer that exhibit elastic properties, meaning they can stretch and return to their original shape.

Recognize the physical state of elastomers: Elastomers are typically rubbery solids at room temperature due to their flexible polymer chains.

Consider the context of the statement: The statement claims that elastomers are rubbery solids, which aligns with the general characteristics of elastomers.

Evaluate the statement based on the definition and characteristics of elastomers: Since elastomers are indeed rubbery solids, the statement is consistent with the known properties of elastomers.

Conclude the evaluation: Based on the understanding of elastomers as rubbery solids, the statement is true.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Elastomers

Elastomers are a class of polymers characterized by their elastic properties, allowing them to stretch and return to their original shape. They are typically composed of long, flexible chains that can undergo significant deformation under stress. Common examples include natural rubber and synthetic materials like silicone and polyurethane.

Rubbery Solids

Rubbery solids refer to materials that exhibit both solid and liquid-like properties, particularly the ability to deform elastically when a force is applied. This means they can stretch and compress without permanent deformation, making them ideal for applications requiring flexibility and resilience, such as in tires and seals.

True or False Statements

True or false statements are assertions that can be evaluated for their accuracy based on established facts or definitions. In the context of chemistry, understanding the properties of materials, such as elastomers, is essential for determining the truthfulness of such statements. This evaluation often relies on knowledge of material science and polymer chemistry.
