Why a gas cools when it expands at high pressure?
When a gas expands at high pressure, it does work on its surroundings to overcome the external pressure. This work done by the gas results in a decrease in its internal energy, leading to a decrease in temperature as per the first law of thermodynamics. So, the gas cools down as it expands at high pressure.
What states is the particle are the far apart and move around with high energy?
The highest energy state is gas.
Do particles of a gas have lots of energy?
Yes, particles of a gas have high energy compared to particles in a solid or liquid because they are moving rapidly and have more kinetic energy. This movement and energy is what allows gas particles to spread out and fill the space of their container.
When a solid changes to a liquid energy it is?
Melting. States of mater: Solid > Liquid > Gas > Plasma Low energy -----> High energy
When were the gas prices so high we waited in lines for gas?
1973?
What matter that is characterized by an extremely high energy which is dangerous to living things?
gas
Why is ozone hotter?
First the basic reason is that it is a green house gas. It shields us from the harmful UV light of high energy as a mirror. So it is hotter.
Why is it possible to compress a gas?
Gas molecules are far apart and have high kinetic energy, allowing them to be compressed into a smaller volume.
Why is the particles of a solid have more energy than those of a gas is false?
because a gas is more heated, and heat gives the particles more energy, so in turn the partilces of a gas has more energy
Phase of matter consisting of high-energy particles?
plasma it has gas particles and ions
Do Particles in gas have lots of energy?
Yes, particles in a gas have high kinetic energy because they are constantly moving and colliding with each other and the walls of their container at high speeds. This movement is what gives gases their ability to expand and fill the space they are in.
Why does gas have the most kinetic energy?
Gas particles have the most kinetic energy compared to solids and liquids because they move more freely and have higher average speeds. In a gas, particles have more space between them and they can move in all directions with high energy, resulting in a higher kinetic energy overall.
