Question

What instrument would you use to (a) measure the length of your bed? (b) measure the amount of acid delivered by a beaker? (c) determine whether you have a fever?

Short answer

Answer: (a) A measuring tape or ruler would be suitable for measuring the length of a bed. (b) A graduated cylinder or a burette should be used for measuring the amount of acid delivered by a beaker. (c) A medical thermometer is an appropriate instrument for determining whether someone has a fever.

Step-by-step solution

(a) Measuring the length of a bed

To measure the length of the bed, we would use a measuring tape or a ruler. A measuring tape is typically more versatile for measuring larger lengths, such as the length of a bed, as it can be more easily extended over long distances and around curves.

(b) Measuring the amount of acid delivered by a beaker

To measure the amount of acid delivered by a beaker, we would use a graduated cylinder or a burette. Both instruments are designed to accurately measure volumes of liquids, such as acids. Graduated cylinders have volume markings on the side, allowing for a quick reading of the volume inside. Burettes are also used for measuring liquid volumes, but they offer more precise measurements due to their finer scale markings and are typically used in titrations.

(c) Determining whether you have a fever

To determine whether you have a fever, we would use a medical thermometer, specifically designed for measuring body temperature. Medical thermometers can come in different forms, such as oral, ear, or forehead thermometers and provide a quick and accurate reading of body temperature to identify if someone has a fever.
