Answer: P=1.63atm
Explanation:
Stp means standard temperature and pressure
Standard temperature =273k
Standard pressure =1atm
Using the formula
P1V1/T1=P2V2/T2
P1= 1atm
V1=5.23L
T1=273k
P2=?
V2=3.45L
T2=293k
Substitute the values
1×5.23/273=p2×3.45/293
Cross multiply
293×1×5.23=p2×3.45×273
1532.39=941.85p2
P2=1532.39/941.85
P2=1.627
P2=1.63atm
Answer:
The sun would appear to move more slowly across Mercury's sky.
Explanation:
This is because, the time it takes to do one spin or revolution on Mercury is 176 days (which is its period), whereas, the time it takes to do one spin or revolution on the Earth is 1 day.
Since the angular speed ω = 2π/T where T = period
So on Mercury, T' = 176days = 176 days × 24 hr/day × 60 min/hr × 60 s/min = 15,206,400 s
So, ω' = 2π/T'
= 2π/15,206,400 s
= 4.132 × 10⁻⁷ rad/s
So on Earth, T" = 1 day = 1 day × 24 hr/day × 60 min/hr × 60 s/min = 86,400 s
So, ω" = 2π/T"
= 2π/86,400 s
= 7.272 × 10⁻⁵ rad/s
Since ω' = 4.132 × 10⁻⁷ rad/s << ω" = 7.272 × 10⁻⁵ rad/s, <u>the sun would appear to move more slowly across Mercury's sky.</u>
Answer:
yes
Explanation:
because chemical wheathering could wheather it away into a ditch
Answer:
12.4 × 10∧3 atoms
Explanation:
Given data:
moles of oxygen molecule= 1.0000 x 10-20 mol
atoms =?
Solution:
32 g O2 = 1 mol = 6.02 × 10∧23
1.0000 x 10∧-20 mol × 6.02 × 10∧23 × 2 = 12.4 × 10∧3 atoms
Humans disturb the earth and because of this, the earth is weakened
