What are gases answer?
Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy.
How is water related to gas?
As water is boiled, kinetic energy causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas (steam or water vapor). When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding.
What describes a gas going to a liquid?
When a gas changes into a liquid, it is called condensation.
Why is the analogy of a greenhouse used to describe the Earth’s atmosphere?
A different analogy is the atmosphere acting like a blanket. Think of yourself under a blanket in a cold room. Adding more greenhouse gas to the atmosphere increases the amount of absorption and release of heat energy required for the energy from the surface to reach the top of the atmosphere and go off into space.
What is water gas Class 11?
A mixture of carbon monoxide and hydrogen produced from passing steam over hot carbon is called water gas. Water gas is a useful product but requires careful handling due to its flammability and the risk of carbon monoxide poisoning.
What is water in the form of a gas called?
Clouds, snow, and rain are all made of up of some form of water. Water existing as a gas is called water vapor. When referring to the amount of moisture in the air, we are actually referring to the amount of water vapor. If the air is described as “moist”, that means the air contains large amounts of water vapor.
What is the process of a gas turning into a liquid?
At a certain temperature, the particles in a liquid have enough energy to become a gas. The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation.
What do greenhouse gases do?
Greenhouse gases are transparent to incoming (short-wave) radiation from the sun but block infrared (long-wave) radiation from leaving the earth’s atmosphere. This greenhouse effect traps radiation from the sun and warms the planet’s surface.
