Volume is an extensive physical property and not an intensive one.
Liquids are similar to gases in that they both have <span>no definite shape.</span>
The speed of sound at 20 oC in air is 343 m/s.
The speed of sound in helium at 20 oC is 927 m/s.
The speed of sound in natural gas (methane) at 20 oC is 446 m/s.
Explanation:
- The speed of sound depends upon the density and elasticity of gas.
- The speed of sound is the distance which is traveled per unit time by a sound wave as it goes through an elastic medium.
- The speed of sound in gas depends only on its temperature and composition.
- Also the speed of sound refers to the speed of sound waves in air.
- Air IS 343 m/s
- Helium is 927 m/s.
- Natural gas (methane) is 446 m/s.
Answer:
Neutral atoms have the same number of electrons and protons. Atoms of an element that contain different numbers of neutrons are called isotopes. Each isotope of a given element has the same atomic number but a different mass number (A), which is the sum of the numbers of protons and neutrons.
