Complete this sentence The electrical conductivity of a sample

Subject : Chemistry

Question: Complete this sentence. The electrical conductivity of a sample will ____________ when the size of the sample increases.

1. decrease

2. stay the same

3. increase

4. be unable to be determined

Expert Verified Solution:

The correct answer is:

2. stay the same

Explanation:

Electrical conductivity is a property of a material that describes how well it can conduct electricity. It is an intrinsic property, meaning it depends on the material’s composition, not on the size or shape of the sample.

When the size of a sample increases, the overall resistance of the material might change because resistance depends on the dimensions of the sample. However, the conductivity, which is the material’s ability to conduct electrical current per unit length and cross-sectional area, will remain the same.

So, regardless of the sample’s size, the electrical conductivity itself stays the same.
