1. isobaric process

In thermodynamics, an isobaric process is a type of thermodynamic process in which the pressure of the system stays constant

2. The First Law of thermodynamics

The First Law of thermodynamics is a formulation of the law of conservation of energy, adapted for thermodynamic processes.

3. heat

In thermodynamics, an isobaric process is a type of thermodynamic process in which the pressure of the system stays constant

4. The wet-bulb globe temperature (WBGT)

The wet-bulb globe temperature (WBGT) is a type of apparent temperature used to estimate the effect of temperature, humidity, wind speed (wind chill), and visible and infrared radiation (usually sunlight) on humans. It is used by industrial hygienists, athletes, sporting events and the military to determine appropriate exposure levels to high temperatures.

5. Wind chill or windchill

Wind chill or windchill (popularly wind chill factor) is the lowering of body temperature due to the passing flow of lower-temperature air. Wind chill numbers are always lower than the air temperature for values where the formula is valid. When the apparent temperature is higher than the air temperature, the heat index is used instead.

6. The heat index (HI)

The heat index (HI) is an index that combines air temperature and relative humidity, in shaded areas, to posit a human-perceived equivalent temperature, as how hot it would feel if the humidity were some other value in the shade.

7. Apparent temperature

Apparent temperature, also known as feels like, is the temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity and wind speed. The measure is most commonly applied to the perceived outdoor temperature.

8. The humidex

The humidex (short for humidity index) is an index number used by Canadian meteorologists to describe how hot the weather feels to the average person, by combining the effect of heat and humidity. The term humidex was coined in 1965.

9. Risk transfer

With reinsurance, the insurer can issue policies with higher limits than would otherwise be allowed, thus being able to take on more risk because some of that risk is now transferred to the re-insurer

10. Risk management

Risk management is the identification, evaluation, and prioritization of risks (defined in ISO 31000 as the effect of uncertainty on objectives) followed by coordinated and economical application of resources to minimize, monitor, and control the probability or impact of unfortunate events
