Explanation

The density of air varies with height.

It is maximum near the surface of the earth and decreases as the height increases.

When we climb up a mountain,

the density of air decreases,

and thus the atmospheric pressure also decreases.

Explanation

An occupational health nurse is responsible for offering:

• health promotion education classes
• and blood pressure
• and cholesterol screenings for the employees
• and their families.

**

The nursing process functions as a systematic guide to client-centered care with 5 sequential steps.

These are

• assessment,
• diagnosis,
• planning,
• implementation,
• and evaluation.

Explanation

Air Commodore Sir Frank Whittle, was an English Royal Air Force air officer. He is credited with inventing the turbojet engine. A patent was submitted by Maxime Guillaume in 1921 for a similar invention; however, this was technically unfeasible at the time.

Explanation

A Steam Turbine is a mechanical device that extracts thermal energy from pressurized steam and transforms it into mechanical work.

Explanation

Relative Humidity Depends on temperature, weather, and location

**

Humidity in the air was measured by a Hygrometer

***

Concept Of Humidity: Important Information: Please read Carefully 

Humidity is the presence of water vapor in the atmosphere.

The higher the rate of temperatures, weather, and (hot) place tend to be the more water vapor rises into the air, and the more humidity that area is.

The lower the rate of temperatures, weather, and (cold) places tend to be the less water vapor rises into the air, and the less humidity that area is.

Explanation

The formula for calculating the density of an ideal gas is d = PM/RT, where: 

• d: is the density of the gas
• P: is the pressure of the gas
• M: is the molar mass of the gas
• R: is the ideal gas constant
• T: is the temperature of the gas in Kelvin

The ideal gas law is expressed as PV = nRT, where 'n' is the number of moles.

Density (d) is mass (m) divided by volume (V), so d = m/V.

We can relate the number of moles (n) to mass (m) and molar mass (M) using n = m/M.

Substituting this into the ideal gas law, we get PV = (m/M)RT.

Rearranging the equation to solve for density (d = m/V), we get d = PM/RT. 

Explanation

Veal is the meat from young calves.

It can come from calves of either sex and any breed.

Most veal is produced from young male calves of dairy breeds not used for breeding.

Veal meat is tender and lighter in color compared to regular beef.

Explanation

In a direct relationship, one variable follows the same change when it comes to increasing and decreasing.

For example,

Ø  when the pressure increases then the temperature also increases.

Ø  When the pressure decreases, then the temperature decreases.

Explanation

Decomposition is slow in deserts due to low moisture and extreme temperatures.

Lack of water limits microbial activity, reducing the breakdown of organic matter.

Explanation

The homogeneous mixture of two or more than two components is called Solution.

Filtration separates solids from liquids using a filter.

Sublimation & Distillation separate components based on phase changes (solid to gas & liquid boiling points).
