When air is removed from the vacuum chamber, the gases in
the balloon will expand to fill the container
. Liquid nitrogen is cold enough to convert carbon dioxide gas particles to a solid. As the particles of carbon dioxide gas get colder, the space between the particles shrinks and the gas changes to a solid.
What state of matter is inside the balloon explain your answer?
Gases
do not have a fixed shape. Think about the balloon again: the gas fills the entire space inside the balloon. You can squeeze the balloon, changing the shape. Gases fill the space available to them.
What happens to particles when they are heated?
When an object is
heated
the motion of the
particles
increases as the
particles
become more energetic. If
it
is
cooled
the motion of the
particles
decreases as
they
lose energy.
What makes Zoes rockets work?
Fizzy headache/vitamin tablets contain a chemical which reacts with water to produce
carbon dioxide gas
. … Once in the air, the liquid coming out of the bottle pushes it along in the same way as the gases coming out of a real rocket propel it upwards.
What happens to the particles of gases when they are under low pressure?
The gas molecules are moving
and are a certain distance apart from one another. An increase in pressure pushes the molecules closer together, reducing the volume. If the pressure is decreased, the gases are free to move about in a larger volume.
Why the force of attraction between solid particles is stronger?
Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. … The
kinetic energy of the molecule is greater than
the attractive force between them, thus they are much farther apart and move freely of each other.
Why do air particles rise if it is heated?
As the molecules heat and move faster, they are moving apart. So air, like most other substances,
expands when heated and contracts when cooled
. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.
What are 3 examples of a gas?
- Hydrogen.
- Nitrogen.
- Oxygen.
- Carbon Dioxide.
- Carbon Monoxide.
- Water Vapour.
- Helium.
- Neon.
Can matter change its state?
It can definitely change its shape, size, and volume
. For examples, water turns into ice upon freezing, here the form of water converts from the liquid state into the solid state; the matter itself doesn't change but it transforms its shape. … Evaporation changes the form of water from liquid state to gaseous state.
What are the 7 states of matter?
Explanation:
Solids, liquid and gas
(the ones we all are familiar with). Then also ionised plasmas, Bose-Einstein condensate, Fermionic condensate, and Quark-Gluon plasma.
Who invented rockets?
American rocketry pioneer
Robert H. Goddard
and his first liquid-fueled rocket, March 16, 1926. Dr. Robert Hutchings Goddard (1882-1945) is considered the father of modern rocket propulsion.
What fuel do rockets use?
Despite criticism and early technical failures, the taming of
liquid hydrogen
proved to be one of NASA's most significant technical accomplishments. . . . Hydrogen — a light and extremely powerful rocket propellant — has the lowest molecular weight of any known substance and burns with extreme intensity (5,500°F).
How do you make homemade flying rockets?
Baking soda and vinegar
rocket
Rockets made of baking soda and vinegar are a great chemistry lesson for kids. All you need is baking soda, vinegar, a paper towel, three pencils, some tape, and a plastic soda bottle. This basic chemical reaction can launch the rocket up to 100 feet.
What eventually happens to a gas if its pressure is increased?
Boyle found that when the pressure of gas at a constant temperature is increased,
the volume of the gas decreases
. … this relationship between pressure and volume is called Boyle's law. So, at constant temperature, the answer to your answer is: the volume decreases in the same ratio as the ratio of pressure increases.
Why do gases expand to fill the container?
Answer: Gases are
in rapid motion
, and they undergo elastic collisions with each other and the walls of the container; that is, momentum and energy is transfered not lost during collisions. Gases expand spontaneously to fill any container (rapid motion).
What happens to gas under extremely high pressure?
When the gas becomes a liquid, however, the volume actually decreases precipitously at the liquefaction point. … High pressure may also
cause a gas to change phase to a liquid
. Carbon dioxide, for example, is a gas at room temperature and atmospheric pressure, but becomes a liquid under sufficiently high pressure.
