Humidity is measured with a hygrometer.

• Hygrometer is a device used to measure humidity in the air.

• There are different types of hygrometers such as psychrometers, capacitive, and resistive hygrometers.

• Humidity can also be measured using a sling psychrometer, which consists of two thermometers - a dry bulb and a wet bulb.

• The difference in temperature readings between the two thermometers is used to calculate the relative humidity.

HVAC system functions by controlling temperature, humidity, and air quality in a building.

• HVAC system pulls in air from the building through return ducts

• Air passes through filters to remove dust and debris

• The air is then heated or cooled by the system's furnace or air conditioner

• The conditioned air is distributed throughout the building via ductwork

• Excess moisture is removed from the air to control humidity levels

Technical development of forest trees involves genetic engineering, biotechnology, and precision breeding.

• Genetic engineering is used to modify the DNA of trees to enhance their growth and resistance to pests and diseases.

• Biotechnology is used to develop new varieties of trees that are more productive and adaptable to changing environmental conditions.

• Precision breeding involves selecting and breeding trees with desirable traits to create new varieties with improved character...read more

The painting process involves applying color to a surface using various techniques and tools.

• Preparation of the surface by cleaning and priming

• Selection of appropriate paint and tools

• Application of paint using brushes, rollers, or sprayers

• Allowing the paint to dry before applying additional coats

• Adding finishing touches such as varnish or sealant

• Examples: oil painting, watercolor painting, spray painting

pH scale is a measure of acidity or alkalinity of a solution on a scale of 0 to 14.

• pH below 7 indicates acidity, with 0 being the most acidic

• pH above 7 indicates alkalinity, with 14 being the most alkaline

• Pure water has a pH of 7, considered neutral

Unit operation refers to a single step in a chemical engineering process.

• Unit operation involves a physical or chemical change to a material

• It is a step in a larger process

• Examples include filtration, distillation, and crystallization

• Each unit operation has its own set of equipment and parameters
