### Three Properties of Metals: 1. **Conductivity**: Metals are generally good conductors of heat and electricity. This property allows them to be used in electrical wiring and cookware, as they can efficiently transfer energy. 2. **Malleability and Ductility**: Metals can be easily shaped when hammered or pressed (malleability) and can be drawn into wires (ductility). This makes them versatile for manufacturing various products, including sheets, wires, and structural components. 3. **Luster**: Many metals have a shiny appearance known as metallic luster. This property makes metals aesthetically pleasing and desirable for decorative items and jewelry. ### Why Paper Towels Must Be Very Absorbent: Paper towels need to be very absorbent to effectively soak up spills, moisture, and other liquids. Their primary function is to quickly and efficiently absorb liquids without falling apart or dripping, allowing users to clean up messes with minimal effort. High absorbency ensures that a paper towel can hold a significant amount of liquid, making it practical for use in kitchens, bathrooms, and other environments where quick clean-up is necessary. ### Why Tissue Paper Is Not Used for Paper Towels: Tissue paper is generally thinner and less durable than paper towels. While tissue paper is absorbent, it tends to break down and disintegrate when it comes into contact with liquids, making it unsuitable for cleaning purposes that require substantial strength and resilience. Paper towels are specifically designed to withstand wet conditions and retain their structure during use, making them the more practical choice for absorbing spills. ### Why a Hammer Is Made of Metal but Has a Wooden or Plastic Handle: A hammer's head is made of metal because it needs to be heavy and durable to effectively deliver force for driving nails or breaking objects. The metal head provides the necessary strength to withstand repeated impacts without deforming. The handle, however, is made of wood or plastic for a few reasons: 1. **Shock Absorption**: Wooden or plastic handles absorb shock better than metal, reducing the vibration that travels to the user’s hand. This makes the tool more comfortable to use over prolonged periods. 2. **Weight**: A metal handle would increase the overall weight of the hammer, making it more cumbersome to use. A lighter handle allows for better maneuverability and ease of use. 3. **Grip and Safety**: Wood and certain plastics can provide a better grip, making the hammer safer to use. A non-slip grip is essential for controlling the tool and preventing accidents. These design choices combine to enhance the functionality and usability of the hammer.
