Final answer:
A psychrometer is the instrument used to measure Wet Bulb (WB) and Dry Bulb (DB) temperatures, which are crucial for determining air humidity. The weight of a violin can be measured with a scale, while the volume of a small amount of oregano can be measured using a measuring spoon or graduated cylinder.
Step-by-step explanation:
What instrument is used for the measurement of WB & DB? When referring to WB (Wet Bulb) and DB (Dry Bulb), these are terms commonly used in relation to air properties and psychrometrics, the study of the thermodynamic properties of mixed air and water vapor. The instrument typically used to measure the wet bulb and dry bulb temperatures is called a psychrometer. A psychrometer usually consists of two thermometers, one that is kept moist (to measure the wet bulb temperature) and one that remains dry (to measure the dry bulb temperature).
The measurements taken with a psychrometer are crucial for determining the humidity level in the air, which can impact various environmental and comfort conditions. By comparing the two temperatures, one can calculate the relative humidity and other psychrometric properties necessary for designing air conditioning systems, predicting weather patterns, or understanding the drying processes in industry.
Choose the appropriate tool for the following measurements:
- The weight of a violin - A scale or balance would typically be used to measure the weight of a violin.
- The volume of a small amount of oregano - To measure the volume of a small amount of oregano, a measuring spoon or a graduated cylinder could be used depending on the level of precision required.
