Density is defined as the amount of a mass in a specific volume. Air pressure occurs due to a column of air exerting a force on an area, while the estimation of tightness of air packing in the column is called density.

The correct answers are:

Option 1B. VolumeOption 2A. PressureOption 3B. Density

This can be explained as:

Density is the measure of mass it can hold up to a specified volume and is calculated by the following formula:

$\text{Density} = \frac{\text{Mass}}{\text{Volume}}$

When the air in the column is moving down then the pressure felt on the walls of the tube is called air pressure.The specific amount or the mass occupied in the tube is called a volume. Hence, the tight packaging of the air in the tube constitutes mass.

Therefore, the correct blanks are volume, pressure and density.

Density is the amount of mass in a certain Volume. Air pressure results from a column of air pushing on an area. A measure of how tightly air molecules are packed together is called Density

Option 1B, 2A and 3B

Explanation:

Density is the mass amount of a substance held up to its volume in certainity to a ratio formula. So basically, density = mass per volume of a substance.

Air pressure, on the other hand, is the pressure which is being experienced by the columnar weight of air, when the air in an area is being pushing down.

The amount of mass of the air in the prescribed volume of air constitutes its density and hence the air molecules packed tightly in the volume presumed carries a mass and is noted as the density.

Some technological solutions to problems like global warming meet the specific needs and situations of local communities. an example from india involves converting the solid waste from cattle into clean-burning fuel for cooking. this reduces the amount of greenhouse gases, specifically methane and carbon dioxide, released into the environment from wood fires. when evaluating the feasibility of implementing this solution, computer models are used to weigh costs against benefits. what factor is least likely to impact the decision on adopting this technology?

Some species of wasps are social. the queen starts a colony from scratch each spring. she builds a small nest, and lays and raises a group of female workers. the workers enlarge the nest while the queen continues to lay eggs. unfertilized eggs become males that mate with newly hatched females. all of the wasps except the newly fertilized females die by the summer. which best describes this behavior? a)it is beneficial only to the males that do not fertilize eggs. b)it is beneficial only to the female workers that are not fertilized. c)it is beneficial to each one of the individual colony members. d)it is beneficial to the whole species, but not to all of the individual members.
