what physical property do all the following have in common:glass,water,carbon dioxide,plastic wrap,air?
mass density, specific heat, thermal conductivity, X-ray absorption, and many others
Chemical property
To determine the physical property that all the substances (glass, water, carbon dioxide, plastic wrap, and air) have in common, we need to assess the given options: mass density, specific heat, thermal conductivity, and X-ray absorption.
1. Mass Density: Mass density refers to the amount of mass per unit volume of a substance. It is a measure of how tightly packed the particles are in a given volume. While glass, water, carbon dioxide, and plastic wrap can be described in terms of mass density, air (being a gas) does not have a well-defined mass density. Therefore, mass density cannot be the common property for all listed substances.
2. Specific Heat: Specific heat is the amount of heat energy required to raise the temperature of a substance by a certain amount. While glass, water, and plastic wrap have specific heat values, carbon dioxide (being a gas) and air (a mixture of gases) have variable specific heat capacities depending on temperature. Therefore, specific heat cannot be the common property for all listed substances.
3. Thermal Conductivity: Thermal conductivity is a measure of a material's ability to conduct heat. Glass, water, plastic wrap, and carbon dioxide all have specific thermal conductivity values. However, as air is a poor conductor of heat, it does not have a significant thermal conductivity. Therefore, thermal conductivity cannot be the common property for all listed substances.
4. X-ray Absorption: X-ray absorption refers to the ability of a substance to absorb X-rays. While glass, water, and plastic wrap have certain X-ray absorption capabilities, carbon dioxide and air are transparent to X-rays, meaning they do not significantly absorb X-rays. Therefore, X-ray absorption cannot be the common property for all listed substances.
Considering the options mentioned, none of them are applicable as a common property for all the substances listed (glass, water, carbon dioxide, plastic wrap, and air). However, there are other properties like being transparent (as glass, water, and plastic wrap are transparent substances), being composed of atoms or molecules, and having a boiling and melting point that differ for each substance.
In conclusion, based on the properties provided, there is no single physical property among mass density, specific heat, thermal conductivity, and X-ray absorption that is common for all the substances mentioned.
