Answer:

hello, the first one is they are both do to heat and more water in sea level makes sea level higher. and i am not sure if the last questions are suppose to be true or false but here u go. 2nd question Sea level changes due to uplift or subsidence of the continental crust. and they change due to volume. 3rd question is if u put something in water it is going to rise. 4th one is yes . and the last one is yes

i am not sure if this is right but hope it helps

Name 2 physical properties that would allow differentiation between copper, lead and iron shot.

Olegator [25]

Answer:

Two physical properties that would allow differentiation between copper, lead and iron shot are - Color and Density

COPPER - Color - Copper has a reddish brown color .

 Density - Density of copper is 8.96 $g/cm^{3}$

LEAD - Color - Lead is grey in color.

Density - Density of Lead is 11.34 $g/cm^{3}$ 

IRON SHOT - Color- Iron shot is in grey color with extra shine .

 Density - Density of iron shot is 10.49 $g/cm^{3}$

Explanation:

COPPER- Copper (Cu) is a reddish, highly ductile metal that belongs to Group 11 (Ib) of the periodic table and is a particularly excellent conductor of electricity and heat. Copper is found in nature in its free metallic state.

LEAD- Lead (Pb) is a soft, silvery white or grayish metal in Periodic Group 14 (IVa). Lead is a weak conductor of electricity and is very malleable, ductile, and thick. Lead, which has been known since antiquity and is considered the oldest of metals by alchemists, is extremely durable and corrosion-resistant, as evidenced by the continued use of lead water pipes constructed by the ancient Romans.

IRON SHOT - Small round iron balls used as projectiles are known as iron shot. Balance scales are used with simple weights. Iron balls are used in the shot put competition.

Hence , the differentiation is mentioned in the above answer.

What is the density of a 15cm3 iron bar that has a mass of 120g?

svet-max [94.6K]

Answer:

The density of an iron bar is 8 g/cm3

Explanation:

The density (δ) is the ratio between the mass and the volume of a compound:

δ=m/v= 120 g/15 cm3= 8 g/cm3
