Step 1:I'll solve this problem step by step, explaining the difference between intensive and extensive properties.
Step 2:: Understanding Intensive and Extensive Properties
- Intensive properties are independent of the amount of substance present - Extensive properties depend on the amount of substance present - Key difference: If you divide the substance, intensive properties remain the same, while extensive properties change proportionally
Step 3:: Malleability
- $$malleability = \text{independent of sample size}
- Malleability is the ability of a material to be hammered or pressed into thin sheets - This property depends on the material's inherent characteristics - Therefore, malleability is an INTENSIVE property
Step 4:: Length
- $$length = \text{dependent on sample size}
- Length measures the distance between two points - Length changes proportionally with the amount of material - If you double a sample, its length doubles - Therefore, length is an EXTENSIVE property
Step 5:: Hardness
- $$hardness = \text{independent of sample size}
- Hardness measures a material's resistance to deformation - This property is characteristic of the material itself - Hardness remains constant regardless of sample size - Therefore, hardness is an INTENSIVE property
Step 6:: Volume
- $$volume = \text{dependent on sample size}
- Volume measures the three-dimensional space occupied by a substance - Volume changes proportionally with the amount of material - If you double a sample, its volume doubles - Therefore, volume is an EXTENSIVE property
Final Answer
- Malleability: INTENSIVE - Length: EXTENSIVE - Hardness: INTENSIVE - Volume: EXTENSIVE
