Using the words biometer chronometer hydrometer micrometer perimeter phonometer thermometer put them in the correct order in sentences below. PLEASE CORRECT ME IF I'M WRONG!!

1.The THERMOMETER registered an increase in temperature.
2.He used a BIOMETER to determine which items would float.
3. The audio technician required a PHONOMETER to determine the correct volume for recording.
4.THe contractor needed to know the exact PERIMETER of the building.
5.The CHRONOMETER calculated the exact time it took for the bullet to reach the target.
6.A HYDROMETER measures the output of organisms in chemically treated soils.
7. A MICROMETER was attached to the microscope was attached to the microscope to determine the diameter of the cell.

You have 2 and 6 reversed.

1. The THERMOMETER registered an increase in temperature.

Explanation: A thermometer is a device used to measure temperature. In this sentence, it is used correctly to indicate that the thermometer detected a rise in temperature.

2. He used a BIOMETER to determine which items would float.
Correction: The correct word here should be HYDROMETER.
Explanation: A hydrometer is a device used to measure the density or specific gravity of a liquid. It is commonly used to determine whether an object will float or sink in a liquid.

3. The audio technician required a PHONOMETER to determine the correct volume for recording.
Explanation: A phonometer is not a commonly used term. The correct device to measure sound level is called a sound level meter or decibel meter.

4. The contractor needed to know the exact PERIMETER of the building.
Explanation: The perimeter refers to the boundary or total length of the outer edges of a two-dimensional shape, such as a building. In this sentence, the word "perimeter" is used correctly.

5. The CHRONOMETER calculated the exact time it took for the bullet to reach the target.
Explanation: A chronometer is a highly accurate timepiece or device used to measure time precisely. In this sentence, the word "chronometer" is used correctly to indicate that it determined the precise time taken for the bullet to reach the target.

6. A HYDROMETER measures the output of organisms in chemically treated soils.
Explanation: A hydrometer is a device used to measure the density or specific gravity of a liquid, not the output of organisms in soil.

7. A MICROMETER was attached to the microscope to determine the diameter of the cell.
Explanation: A micrometer is a device used to measure small distances or dimensions. In this sentence, it is correctly used to indicate that it was attached to the microscope to measure the diameter of the cell.
