Answer:
See answer below
Step-by-step explanation:
the ratio of pv against nrt is called compressibility Z and measures the deviation from an ideal gas behaviour . When Z is plotted against pressure for CH₄ for 0°C and 200°C the curves will differ because there are
- negative deviations ( Z decreases) due to intermolecular forces
- positive deviations (Z increases ) due to molecular size of gas particles
then
- at 0°C the negative deviations prevail respect to positive deviations at lower pressures ( so Z drops below the horizontal line first ) and then Z increases when pressure increases since the effect of positive deviation is higher ( then Z increases)
- Nevertheless, at 200°C the effect of intermolecular forces is lower and thus the positive deviations always prevail ( thus you observe only Z increasing(
Answer:
1205.76
Step-by-step explanation:
The formula for volume of a cylinder is : π(or 3.14)r²h
Plug in the variables and solve
(3.14)(8)²(6)
(3.14)64(6)
384(3.14)
1205.76
Hope this helps
The <em><u>correct answer</u></em> is:
22.5° F.
Explanation:
The temperature increases 1.5° per hour. From 5:00 AM to 12:00 PM is 12-5 = 7 hours. This makes an increase of 1.5(7) = 10.5°.
The temperature started at 12°F; increasing by 10.5° gives us
12+10.5 = 22.5°F.

Answer:
8 sand bags
Step-by-step explanation:
300 - 140 = 160
160 ÷ 20 = 8
8 sand bags of 20-pounds each.
