What does a solid do when it contracts?
When a solid freezes, it contracts making the molecules inside get closer together which makes the volume smaller.
What happens to density as an object contracts?
As an object contracts, its volume decreases while its mass remains constant. This results in an increase in the density of the object since density is defined as mass divided by volume.
What is a smooth muscle that contracts or relaxes to change the volume of the chest?
The Diaphragm.
What is the name of the large muscle that contracts and causes the lungs volume to increase?
the diaphram
The diaphragm contracts during what phase of respiration?
The diaphragm contracts during the inhalation phase of respiration. When it contracts, it moves downward, increasing the volume of the thoracic cavity and causing air to rush into the lungs.
What is the purpose of a contract management system?
If a company has a high volume of contracts managing them can be tough. A contract management system will make keeping track of contracts easy.
How does the diagram help us breath?
it contracts, pulling downwards to increase the volume in the chest.
When does the lung relax?
The lung doesn't relax, it is controlled by the diaphragm When it relaxes the volume of the lungs decrease during expiration When it contracts the volume of the lungs increases during inhilation
What increases the volume of the chest when it contracts?
the lungs push against your chest when you breathe causing an almost flexing motion
What happened to the volume of water and the wax after freezing?
When water freezes, it expands and takes up more space, causing its volume to increase. In contrast, when wax freezes, it contracts and becomes more dense, resulting in its volume decreasing.
What occurs to the volume of an inflated balloon when exposed to cold air?
It decreases. The colder air contracts, making the balloon shrink.
What happens to particles when an object expands and contracts?
When an object expands, the particles within the object move farther apart from each other, increasing the object's volume. When the object contracts, the particles move closer together, decreasing its volume. This expansion and contraction occur due to changes in temperature, pressure, or other external factors.
