what is the properties of coin,spring and balloon
Answer (1)
1. CoinMaterial - Usually made of metal (e.g., copper, nickel, zinc)Hardness - Hard and solidShape - Flat and circularDensity - High density (heavy for its size)Conductivity - Good conductor of heat and electricityDurability - Resistant to wear and corrosion (depends on metal type)Inelastic - Does not easily change shape under force2. SpringMaterial - Usually made of metal wire (steel or alloy)Elasticity - Highly elastic; can stretch or compress and return to original shapeFlexibility - Flexible and can store mechanical energyShape - Helical or coiledStrength - Can withstand repeated stretching and compressing without permanent deformationTensile strength - High, depending on material3. BalloonMaterial - Usually made of rubber or latexElasticity - Highly elastic; can stretch significantly when inflatedFlexibility - Very flexible and can expand to hold air or gasLightweight - Very light and thinPermeability - Slightly permeable to gases (air slowly escapes over time)Fragility - Can burst if overinflated or punctured
