Yes someone can even have a bigger looking arm but have less dense muscle than another person. Dense muscle is built by HEAVY lifting.
muscle is more dense, hence heavier.
yes and it weighs more to.
A pound of fat weighs the same as a pound of muscle. There is no difference. However, they do differ in density. Muscle tissue tends to be more dense than fat tissue because it has more water. This means that a muscular person would generally displace less water (have less volume) than a fat person of the same weight, and that a muscular person would weigh more than a fat person who displaces the same amount of water (equal volume).
Yes. Muscle is more dense than fat. As you gain muscle mass, you do gain weight.
Generally, it is not the weight so much as the amount of fat to lean muscle and bone. The more fat a person has the more buoyant they are. You could a have 300-pound weightlifter who is solid muscle (very dense) and a 300-pound elderly man who has little lean muscle and lots of fat. The elderly man would be more buoyant even though their weight is the same.
An object will float in a substance if it is less dense that it, and if they are more they will sink. Water is 1g/mL, and most people are quite similar to this (so close that usually if someone in water breathed out, they sink, breath in, they float). What makes the difference is not how much someone weighs, but their density, which depends on how much muscle and fat they have. Fat is actually less dense than water - so having more fat will actually make a person more bouoyant. Muscle is more dense than water so a person having more muscle will sink. So a person weighing 240 pounds could float while a 160 pound person could sink - it depends on what their body is like.Because of their density: People with a lower body fat percentage (fat is less dense than water) sometimes cannot stay on the surface of the water without motion to propell themselves upwards, although most people *do* remain at the surface if they relax and lean back.Bone is considerably more dense than water, muscle is a little more dense, and fat less dense.If the weight of water you displace is less than your own weight, you will sink.
This is a common myth. The easiest way to understand this is to look at it this way... 5 lbs. of fat is much bulkier than the 5 lbs. of muscle, but five pounds is still five pounds. Muscle does not weigh more than fat. Fat is bulky and lumpy so if you carry an extra five pounds of fat, you'll be lumpier than with five pounds more muscle. A five pound pile of fat will take up more space (volume) than a five pound pile of muscle; but five pounds is still five pounds. A woman weighing 150 pounds with 19% fat will look much smaller (and be much healthier) than a woman at 150 pounds with 35% fat. They weigh the same, yet the composition is different. Because muscle is more dense than fat the person with less fat and more muscle will look smaller.
Muscle tissue is called just that. It is not as pliable as other tissue in the body and it is much more dense. Muscle tissue can be found in every area of the body.
Fat is less dense than water, while muscle and bone are more dense. A person with a higher fat percentage will displace his weight with less of his volume submerged, so he will float higher.
Stop exercising them. The muscle will atrophy. (Also, you'll probably lose weight rather than gain it; muscle is more dense than fat.)
When a person becomes older, there bones will become more dense. When bones are more dense, they can break easily.
Skeletal muscle contributes more weight in a person's body than any other muscle type. It accounts for 40% of a person's total weight.
