Short answer

Answer: The appropriate instruments are a scale for measuring the mass of the lettuce, a thermometer for the temperature of the water, and a measuring cup or graduated cylinder for the volume of the orange juice.

Step-by-step solution

Identify the instrument for measuring mass

The appropriate instrument for measuring the mass of a head of lettuce would be a scale, which can be expressed as a digital or analog balance.

Identify the instrument for measuring temperature

To determine whether the refrigerator is cooling water to \(10^{\circ} \mathrm{C}\), the appropriate instrument to use is a thermometer, which can be a digital or analog thermometer designed for use with liquids.

Identify the instrument for measuring volume

For measuring the volume of a glass of orange juice, a measuring cup or graduated cylinder is an appropriate tool to use, which can be made of glass or plastic and contains multiple unit marks to determine volume in either milliliters or ounces.
