Pressure has the opposite effect on air density increasing the pressure increases the density
In decomposition, two or more reactant combine to form one product only.
The deeper the diver takes the helium balloon, the more it reduces in size. This is due to the pressure of the water column above pressing on the balloon. According to Boyle’s law (P= k*1/V.), as the volume of the balloon decreases, the pressure of the helium inside increases.
Helium gas: He
Hydrogen gas: H₂
Oxygen gas: O₂
Explanation:
Gases can exist at room temperature in monoatomic form or sometimes as polyatomic molecules.
A wide range of elements exists as gases at room temperature. Most of their molecules have covalent bonds between their atoms which ensures that they are stable.
Other examples are:
- Argon gas Ar
- Neon gas Ne
- Bromine gas Br₂
- Nitrogen gas N₂
