To determine in which box salt could be placed, we need to understand the physical state of salt at room temperature and match it with the descriptions provided in the table.

Here's a step-by-step approach to solving the problem:

1. Identify the Physical State of Salt:
- At room temperature, salt (sodium chloride, NaCl) exists in a solid state.

2. Understand the Characteristics of a Solid State:
- In a solid state, atoms or molecules are closely packed together.
- They do not move freely but rather vibrate in place.

3. Examine the Table:
- Box T describes an arrangement where atoms are fixed and vibrate in place. This matches the description of the solid state where atoms or molecules are closely packed and vibrate in place.
- Box U describes an arrangement where atoms move freely and spread out, characteristic of a gas.
- Box liquid describes an arrangement where atoms are closely packed but slide past one another, characteristic of liquids.
- Box V describes an arrangement where particles are rapidly moving and ionized, characteristic of plasma.

4. Match Salt with the Appropriate Box:
- Since salt is in the solid state at room temperature, and the solid state description matches the characteristics given in Box T, salt could be placed in Box T.

Therefore, salt could be placed in box T.
