erosion is geosphere and glaciers are cyrosphere
Density = mass divided by volume. 15/30 is 1/2 so the density is 1/2 or 0.5 g/cm
Answer:
the answer is second option. with 2 models
Explanation:
2H2 + O2 gives 2H2O
so there's two models
Answer : The correct statement is:
The density of each piece is the same as that of the original block.
Explanation :
Intensive property : It is defined as a property of substance which does not change as the amount of substance changes.
Examples: Temperature, refractive index, density, hardness, etc.
According to question, if Ana has a block made of pure gold and she cuts this block into two equal pieces then the density of each piece is the same as that of the original block because density is an intensive property that does not changes until and unless material is changed.
That means density remains same as that of the original piece.
Hence, the correct statement is the density of each piece is the same as that of the original block.
<u>Given:</u>
Moles of gas, n = 1.50 moles
Volume of cylinder, V = 15.0 L
Initial temperature, T1 = 100 C = (100 + 273)K = 373 K
Final temperature, T2 = 150 C = (150+273)K = 423 K
<u>To determine:</u>
The pressure ratio
<u>Explanation:</u>
Based on ideal gas law:
PV = nRT
P= pressure; V = volume; n = moles; R = gas constant and T = temperature
under constant n and V we have:
P/T = constant
(or) P1/P2 = T1/T2 ---------------Gay Lussac's law
where P1 and P2 are the initial and final pressures respectively
substituting for T1 and T2 we get:
P1/P2 = 373/423 = 0.882
Thus, the ratio of P2/P1 = 1.13
Ans: The pressure ratio is 1.13
