Physical properties of a substance include, solubility, boiling point, etc.
The correct matching of the physical properties with definition is as follows;
- Solubility - the ability of a substance to dissolve in another
- Boiling point - the temperature at which a liquid becomes a gas
- Density - the amount of mass in a given volume
- Buoyant force - the upward force on an object in a fluid
- Conductivity - the ability of a substance to transfer heat or electricity
Above, all the physical properties have been properly matched with the corresponding definitions.

A. potential energy.
It can't be any of the above questions. When the automobile burns gas it converts the potential energy into chemical energy which intern gets converted into mechanical energy and then into kinetic energy.
I would have thought it would be Chemical potential energy, which is referring to the energy between the bonds in the molecule.
Hoped this helped.
Answer:
A
Explanation:
You want an equation that includes both V and T. Charles' Law states that V =kT or V₁/T₁ = V₂/T₂, so this is the best formula to use.
B: The Combined Gas Law is p₁V₁/T₂ = p₂V₂/T₂ will work, but it's overkill for the situation. You can assume any constant value for the pressure, and it will cancel from each side of the equation,
C is wrong. Boyle's Law is p₁V₁ = p₂V₂. It does not include the temperature.
D is wrong. Gay-Lussac's Law is p₁/T₂ = p₂/T₂. It does not include the volume.
They have different ratios of elements. Water is H20 and Hydrogen Peroxide is H202. The extra oxygen atom in hydrogen peroxide causes it to be structured and react differently.
At STP (standard temperature and pressure), one mole of a gas occupies 22.41 liters of volume. Avogadro's number (6.022*10^23) is the number of molecules per mole of a substance, or one mole of anything really. This means there are 6.022*10^23 molecules of any gas with a volume of 22.41 L at STP.
