Q1: What is the primary difference between solids, liquids, and gases?
A1: The primary difference lies in the arrangement and energy of molecules. Solids have tightly packed molecules with low energy, liquids have loosely packed molecules with moderate energy, and gases have very loosely packed molecules with high energy.
Q2: Can solids, liquids, and gases change their state?
A2: Yes, they can. For example, a solid can melt into a liquid, a liquid can evaporate into a gas, and a gas can condense into a liquid.
Q3: Why are gases more compressible than solids and liquids?
A3: Gases are more compressible because their molecules are far apart and can be brought closer together easily compared to the tightly packed molecules in solids and liquids.
Q4: How do the densities of solids, liquids, and gases compare?
A4: Solids have the highest density, followed by liquids, and gases have the lowest density.
Q5: What are intermolecular forces, and how do they vary in solids, liquids, and gases?
A5: Intermolecular forces are the forces of attraction between molecules. These forces are strongest in solids, moderate in liquids, and weakest in gases.
Q6: Why do liquids have a fixed volume but no fixed shape?
A6: Liquids have a fixed volume because their molecules are close enough to resist compression, but they do not have a fixed shape because the molecules can move past each other, allowing the liquid to take the shape of its container.
Q7: In what conditions do gases condense into liquids?
A7: Gases condense into liquids when they are cooled to their condensation point or when they are subjected to increased pressure.
Q8: Can all substances exist in solid, liquid, and gas states?
A8: Most substances can exist in all three states under the right conditions of temperature and pressure, although some substances decompose rather than changing state.
Q9: How does temperature affect the states of matter?
A9: Increasing temperature generally increases the energy of molecules, causing solids to melt into liquids and liquids to evaporate into gases. Decreasing temperature has the opposite effect.
Q10: What is sublimation?
A10: Sublimation is the process where a solid changes directly into a gas without passing through the liquid state, such as dry ice turning into carbon dioxide gas.
Understanding the characteristics, advantages, disadvantages, and similarities of solids, liquids, and gases helps in comprehending the behavior of matter under various conditions and is crucial for numerous scientific and practical applications.

Introduction
Commercial Banks and Development Banks play pivotal roles in the financial system, catering to different needs and segments of the Economy. Commercial banks primarily focus on providing financial Services to individuals and businesses, facilitating day-to-day financial transactions and short to medium-term credit needs. Development banks, on the other hand, are specialized financial institutions designed to provide long-term capital for Economic Development projects. Understanding the key differences, advantages, disadvantages, and similarities between these two Types of Banks can provide a clearer picture of their roles and impacts on the economy.
Key Differences Between Commercial Banks and Development Banks
| Feature | Commercial Bank | Development Bank |
|---|---|---|
| Purpose | Profit maximization | Economic development and social welfare |
| Primary Function | Accepting deposits and providing loans | Providing long-term financing for development projects |
| Clientele | General public, businesses | Governments, large-scale industries, Infrastructure-2/”>INFRASTRUCTURE projects |
| Funding Sources | Deposits from public, inter-bank loans | Government funding, international agencies, Bonds |
| Loan Duration | Short to medium-term (up to 5 years) | Long-term (over 5 years, often 10-20 years) |

Frequently Asked Questions (FAQs)
The main difference lies in their objectives. Commercial banks focus on profit maximization through providing a variety of financial services to the public, while development banks aim to promote economic development by providing long-term financing for development projects.
How do commercial banks generate profits?
Commercial banks generate profits primarily through the interest charged on loans, fees for various services, and investments in Financial Markets.
Why are development banks important for economic growth?
Development banks are important for economic growth because they provide long-term financing for projects that can lead to industrialization, Infrastructure Development, job creation, and overall economic improvement, which might not be attractive to commercial banks due to higher risks and longer payback periods.
Can a development bank provide services similar to a commercial bank?
While the primary focus of development banks is different, some development banks may offer similar services as commercial banks, such as deposits and short-term loans, but this is usually limited.
What are the typical sources of funding for development banks?
Development banks typically receive funding from government budgets, international development agencies, issuing bonds, and sometimes from commercial sources.
How do commercial banks manage risks?
Commercial banks manage risks through stringent credit assessment procedures, diversifying their loan portfolios, maintaining adequate capital reserves, and using financial instruments like insurance and Derivatives.
Are development banks more prone to political influence?
Yes, since development banks often rely on government funding and are involved in projects aligned with national development goals, they can be more susceptible to political influence compared to commercial banks.
What role do international development agencies play in development banks?
International development agencies provide financial Resources, technical expertise, and policy advice to development banks to help them achieve their developmental goals.
Can individuals open accounts in development banks?
Generally, development banks do not offer personal banking services as commercial banks do. Their focus is on financing large-scale projects and providing specialized financial services.
What challenges do development banks face?
Understanding these differences, advantages, disadvantages, and similarities can help stakeholders make informed decisions regarding the utilization of commercial and development banks for various financial and developmental needs.
