Cold air is more dense than warm air. This is why cold air masses tend to descend, and warm air masses tend to rise.

Who of the balls of equal masses and different sizes have lower density?
If two perfect spheres of different sizes have the same mass, then the larger ball has a lower density and the smaller ball has a higher density. This is because density is the amount of mass in a given volume, and density is obviously higher if there is a smaller volume for a given amount of mass.
Can two objects have the same volume but not the same density?
no density equals mass divided by volume. if both solids have a mass of 100 grams (for example) one has a volume of 100 mL (or centimeters cubed), it's density is 1 g/mL if the other has a volume of only 50 mL it's density is 2 g/mL
What is the formular for mass?
Formula Mass is the average mass of a molecule calculated as the sum of the individual atomic masses.
How Mass and volume can affect the density of the volume?
The definition of density is mass per unit volume. For any object or sample of a substance, it can be calculated as (mass) divided by (volume). If two objects or samples with the same volume have different masses, the one with the greater mass has greater density. If two objects or samples with the same mass have different volumes, the one with the greater volume has smaller density.
Equal volumes always mean equal masses?
Other things being equal, yes; in general, no. The mass also depends on the density.
What causes air mass to move?
The temperature and density of the air masses. the air masses moves when hot air and cold air gets together
How air mass moves?
The temperature and density of the air Masses.the air masses move when cold air and hot air gets together.
When warm air mass is stuck between two cold air masses What kind of front type is it?
stationary
When a warm air mass overtakes a cold air mass it form a?
Yes. Cold air masses have higher density, because the molecules are closer together. That makes them have higher pressure because there is more mass per unit volume pressing
How is it possible for objects to have the same volume but different masses?
Their masses are different. (Mass = density * volume)
What kind of weather is likely to occur if warm air masses move over a cold air mass?
cool weather
How does the atmosphere circulate as air masses?
The atmosphere moves in masses. When two masses collide they are called fronts. When a cold air mass goes into the land occupied by a warm mass it makes a cold front. The opposite makes a warm mass.
How is density affected if two objects have the same volume but different masses?
Greater the mass higher the density and less the mass lower the density as D = M/V For fixed V, density is directly proportional to the mass.
What is a heterogenous mass in the left adnexum?
Heterogenous means of mixed density on an ultrasound. Homogenous would be of only one kind of density. Heterogenous means there are both high density and low density components of a mass. There are several kinds of cysts that can be found on the ovaries, some of which are fluid, some containing blood (which is higher in density), and various masses of soft tissue variety (like dermoids). You need to discuss with your doctor exactly what kind of mass was found in the ovary and what kind of follow up is needed.
Are there different water masses?
pure water has the same density, and the same mass
When a cold air masses replaces a warm air mass its called a front?
Cold
What kind of air would be characteristic of a continental polar air mass?
Continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. As they move into warmer air, they can trigger precipitation.
