Do you believe that the universe is still expanding?
Yes, scientific evidence, such as redshift measurements of distant galaxies, indicates that the universe is still expanding. This expansion is believed to be accelerating due to dark energy, a mysterious force that counteracts gravity at large distances.
The discovery of a red shift in the spectra of galaxies provided evidence that the universe is?
expanding.
Why is the air above a fire blurry?
The blurriness above a fire is caused by heat distortion, which is a result of the air molecules being rapidly heated and expanding. This distortion affects how light travels through the air, creating the blurry effect that we see above a fire.
Why do balloons expand when they go higher?
Balloons expand when they go higher because the air pressure outside the balloon decreases as altitude increases. This decrease in air pressure causes the gas inside the balloon to expand to occupy a larger volume, leading to the balloon expanding in size.
What is the definition for expanding star?
A 'nova'.
What is an example of something expanding contracting?
An example of something expanding and contracting is a balloon. When air is blown into the balloon, it expands. When the air is released, the balloon contracts back to its original size.
What is an example of a solid expanding?
spandex
What is Example of something that is expanding or contracting?
An example of something that is contracting is a deflating balloon, as its volume decreases. An example of something that is expanding is a growing plant, as it increases in size and complexity.
What keeps the lung from fully expanding?
pure air
What is caused by rapidly expanding and contracting air masses?
=== ===
Warm air has higher air pressure than cold air because the molecules are expanding?
False
The victims abdomen has become swollen and is expanding during ventilation what is the cause of this?
Air is going into the stomach and is expanding during ventilation .
What region creates expanding air masses?
Tropical regions near the equator are known for creating expanding air masses due to the intense heating of the surface, which leads to the air rising and expanding as it heats up. This process plays a key role in the formation of convection cells in the atmosphere, such as the Hadley cell.
It is caused by rapidly expanding and contracting air mass?
thunder
If air expands it warms then why does our troposhere gets colder as you get higher?
As you get higher the air is thinning not expanding.
What sound occurs because of rapidly expanding air during a thunderstorm?
lightning
Sound made by rapidly heating and expanding air caused by lightning?
thunder
