The correct answer is A. Density

Explanation:

In chemistry, a physical property differs from a chemical property because physical properties can be observed or determined without changing the substance. Example of this includes color, density or texture while examples of chemical properties include toxicity, flammability, reactivity, oxidation, etc. Density (mass per unit) is classified as part of physical properties because this can be determined by dividing the mass of the substance by its volume which means this property can be measured without altering the substance and therefore it is a physical property.

Hello!

According to the Charles' Law, the volume of a gas is proportional to temperature when pressure is constant. When going from New York to Florida, if the pressure is left constant the volume of the tires will increase.

The final volume of the tires can be calculated from the following equation, derived from Charles' Law:

$V2= \frac{V1}{T1}*T2=\frac{10 L}{10degC}*32degC=32 L$

or to say:

Halogens and noble gases are two different groups of elements that can be seen on the periodic table. Halogens are found in group 17 and include fluorine, chlorine, bromine, iodine and astatine. Noble gases make up group 18, and include helium, neon, argon, krypton, xenon and radon.
