SCERT Class 6 Science Chapter-5 Question Answer "Objects Around Us (जोंनि सोरबिथिंनि बेसादफोर)"
1. Objects and Materials
Objects vs. Materials: An object (बेसाद) is the item itself, while a material (मुवा) is the substance from which the object is made. For example, a notebook is an object, but paper is the material.
Versatility:
- A single object can be made from a mixture of different materials (e.g., a pen is made of metal, plastic, and ink).
- Multiple different objects can be made from the same material (e.g., wood can be used to make chairs, tables, or doors).
Classification (थाखो राननाय): Grouping objects and materials based on their properties, shapes, and uses helps in organizing them systematically and finding them easily.
2. Physical Properties of Materials
Appearance & Luster (बायजोआरि महर आरो गोजोंथाइ):
- Materials differ in appearance, color, and texture.
- Metals (like iron, copper, aluminum, and gold) typically have a characteristic shine or luster.
- Freshly cut or scrubbed metals show luster, though exposure to air and moisture can cause them to lose their shine over time. Materials without luster are non-lustrous.
Hardness (गोराथि आरो गुरैथि):
- Soft Materials (गुरै मुवा): Materials that can be easily compressed, deformed, or scratched (e.g., rubber, cotton).
- Hard Materials (गोरा मुवा): Materials that are difficult to compress or scratch (e.g., iron, stone).
Transparency (गोगोथि):
- Transparent (गोगो): Substances through which objects can be seen clearly (e.g., clear glass, air, water, clear plastic).
- Opaque (गोगोनङि): Substances through which you cannot see at all (e.g., wood, metals, cardboard).
- Translucent (खाव-गोगो): Materials through which objects can be seen, but not clearly (e.g., oily paper, frosted glass).
Solubility in Water (दैआव गलिनाय):
- Soluble (गलिग्रा): Substances that completely dissolve and disappear in water (e.g., salt, sugar, glycerin).
- Insoluble (गलियि): Substances that do not dissolve in water, even after stirring (e.g., sand, chalk powder, sawdust, cooking oil).
- Certain gases also dissolve in water, such as dissolved oxygen, which enables aquatic plants and animals to survive.
Flotation (गोजावनाय आरो गोदोनाय):
- Some materials float on the surface of water because they are less dense than water (e.g., paper boat, dry leaves, bamboo raft).
- Other materials sink to the bottom (e.g., stones, iron nails, coins).
3. Scientific Definition of Matter (मुवा)
Mass (मोदोमबां):
- The amount of matter present in an object is called its mass.
- It is measured using units like grams (g) and kilograms (kg).
Volume (रोजागासै):
- The amount of space an object or substance occupies is called its volume.
- Liquids are commonly measured in milliliters (mL) and liters (L).
Definition of Matter:
- Anything that has mass and occupies space (has volume) is defined as matter.
- Air is proven to be matter because an inflated ball/balloon weighs more than a deflated one (showing air has mass), and trapped air prevents water from entering an inverted glass (showing air occupies space).
