Answer:
2cm^3
Explanation:
Use the density triangle: D=MxV
Switch for variables, V=M/D
Plug in numbers, 15.8g/7.9g/cm^3=2cm^3
Answer:
Temperature decreases and density increases
Explanation:
Let us remember that density of a material increases as the temperature of the material decreases. So the cooler a material becomes, the denser it becomes also.
Between points B and C, the material rapidly cools down and the temperature decreases accordingly. This ultimately results in an increase in density since cooler materials are denser than hot materials.
Answer:
evaporation or water runoff that's my tips
rain or thunder storm
Gamma rays
Explanation:
Gamma rays is a form of electromagnetic radiation. It has zero mass and no charge.
Most radiations are particles but gamma rays are not particles they are mere rays.
- They have an energy range between 10KeV and 3Mev
- The range of gamma rays is not definite but it is very long.
- The intensity of gamma rays for any medium decreases exponentially from the source.
- Gamma rays are ionizing radiations

Answer:
D. the polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions.
Explanation:
<em>Dipole-Dipole interactions</em> take place only between polar molecules.
They consist of attractions between the negative end of a polar molecule and the positive end of another polar molecule. For example, between the O atom and the H atom in water.
These attractions are not present in a non-polar liquid, so its molecules will be more loosely held together and its boiling point will be lower.
