Recycling involves collecting and processing waste materials, such as paper, plastic, glass, and metal, and turning them into new products. This process is important because it helps conserve natural resources by reducing the need for virgin materials, such as trees for paper or ores for metals. Recycling also reduces the amount of waste sent to landfills, decreasing environmental pollution and the strain on landfill capacity. Additionally, recycling reduces energy consumption and greenhouse gas emissions compared to producing new materials from scratch.

Insulators are materials that resist the flow of electricity, meaning they do not conduct electrical currents. Common insulators include rubber, plastic, glass, and wood. These materials are crucial in electrical safety because they prevent the accidental flow of electricity, reducing the risk of electrical shocks, short circuits, and fires. For example, electrical wires are often coated with rubber or plastic insulation to ensure that the current stays within the wire, protecting people and property from harm. Insulators are also used in various applications where electrical separation is necessary.

Transparency is a property of certain materials that allows light to pass through them without being scattered, enabling objects on the other side to be seen clearly. Common transparent materials include glass, which is used in windows and optical lenses; clear plastics, which are used in packaging and containers; and certain crystals, such as quartz. The degree of transparency can vary, with some materials being fully transparent, like window glass, and others being translucent, allowing some light through but not clear images.

Opaque materials are those that do not permit light to pass through them, making them unable to see through. This lack of transparency occurs because their internal structure either scatters or absorbs light rather than letting it travel through.

Opaque materials are those that do not permit light to pass through them, making them unable to see through. This lack of transparency occurs because their internal structure either scatters or absorbs light rather than letting it travel through. For example, materials like wood, metal, and concrete are opaque because their dense, irregular structures prevent light from passing through. As a result, objects behind opaque materials are not visible.

An increase in the temperature of an object means that the thermal energy has increased; option [D]. Temperature is a measure of the average kinetic energy of the molecules within an object. As temperature rises, the molecules move faster, increasing the object’s overall thermal energy. Thermal energy is the total kinetic energy due to the random motion of particles in the object. This increase in thermal energy is not the same as an increase in potential energy, which is related to the position of objects in a field, or mechanical energy, which includes both kinetic and potential energy in a macroscopic system. Therefore, when an object’s temperature increases, its thermal energy increases as well, reflecting the higher kinetic energy of its molecules. Thus, the correct option is [D] Thermal energy has increased.
