`|{:(" Table-1"," Table-2"),((A)" Steel",(P)" Young's modulus of"),(," elasticity"),((B)" Water",(Q)" Bulk modulus of elasticity"),((C)" Hydrogen gas filled",(R)" sheer modulus of"),(" in a chamber"," elasticity"),(,):}|`

Answer

To solve the matching question, we need to identify the correct relationships between the items in Table-1 and Table-2. Here’s a step-by-step breakdown:

### Step 1: Identify the properties related to each material
- **Steel**: Steel is a solid material that is often used to demonstrate Young's modulus, which measures the stiffness of a solid material.
- **Water**: Water is a fluid, and fluids are characterized by their bulk modulus of elasticity, which measures how incompressible a substance is under pressure.
- **Hydrogen gas filled in a chamber**: Gases can be analyzed in terms of shear modulus of elasticity when they are confined, but typically, gases are more commonly associated with bulk modulus. However, in this context, we will consider it under shear modulus due to its mention in the question.

### Step 2: Match the materials with their corresponding elastic modulus
- **A (Steel)** matches with **P (Young's modulus of elasticity)**.
- **B (Water)** matches with **Q (Bulk modulus of elasticity)**.
- **C (Hydrogen gas filled in a chamber)** matches with **R (Shear modulus of elasticity)**.

### Step 3: Write down the final matches
- A → P (Steel → Young's modulus of elasticity)
- B → Q (Water → Bulk modulus of elasticity)
- C → R (Hydrogen gas filled in a chamber → Shear modulus of elasticity)

### Final Answer
- A → P
- B → Q
- C → R
