Air contracts and expands because of changes in temperature. When air is heated, its molecules gain energy and move faster, spreading out and causing the air to expand. Conversely, when air is cooled, its molecules lose energy and move slower, coming closer together and causing the air to contract.
The lungs are like a balloon because they expand and contract as we breathe, similar to how air fills and exits a balloon.
The lungs can expand and contract due to the presence of specialized muscles called the diaphragm and intercostal muscles that help regulate the volume of the thoracic cavity. When these muscles contract, the volume of the chest cavity increases, causing air to flow into the lungs (inhalation). When these muscles relax, the volume decreases, causing air to flow out of the lungs (exhalation).
Yes, gases can both expand and contract. When heated, gases expand as the molecules move more rapidly, increasing the pressure and volume. Conversely, when cooled, gases contract as the molecules slow down, decreasing the pressure and volume.
The balloon would shrink in size as the air inside cools and contracts. This is because gases, like the air in the balloon, contract when they are cooled and expand when they are warmed.
Yes, water pipes in homes can expand and contract due to changes in temperature. When pipes are exposed to heat, they expand, and when they cool down, they contract. This expansion and contraction can lead to stress on the pipes, potentially causing leaks or damage over time.
to pull in air and break out air
The chamber of a barometer will contract as air pressure goes up. A rise in air pressure pushes the mercury column downward, causing the chamber at the top to become smaller.
do you mean fills with air? if so then its the lungs
Expand
explain how temperature affects matter using the words contract and expand
Expand
They have to either expand or contract through movement. They can only expand and contract as far as their tissues will allow,
It will contract.
Inspiration - the process of breathing in. The lungs expand and take in air.
All rock can expand or contract.
"EXPAND"
They expand.
