Answer:
final temperature is 469.71 K = 196.71 °C
Explanation:
Given data
volume V = 1010 cm3 = 0.00101 m³
temperature = 20.7°C = 20.7 + 273 = 293.7 K
pressure P1 = 1.04 x 10^5 Pa
volume = 1570 cm3
pressure P2 = 1.07 x 10^5 Pa
to find out
number of moles of oxygen and final temperature
solution
we know that for ideal gas
PV = nRT
put here all value to get n
R gas constant = 8.314472 J/mol−K and T = 293.7 K and V = 0.00101 m³
and P = 1.04 x 10^5
so n = ( 1.04 x 10^5 × 0.00101 ) / ( 8.314472 × 293.7 )
n = 0.043015 moles
and
now we use equation
P1V1 /T1 = P2V2 / T2
1.04 x 10^5 × 1010 / 293.7 = 1.07 x 10^5 × 1570 / T2
T2 = 49338663 / 105040 = 469.71 K
so final temperature is 469.71 K = 196.71 °C
Answer:
Deep ocean trenches
Explanation:
Subduction zones are Earth's lithosphere (the crust and as well as the upper non-convecting part of the upper mantle) gravitational collapsing sites. Along convergent plate boundaries, subduction zones exist where one sheet of oceanic lithosphere merges with any other layer. So, in order to find depth of water in the sea, we can find these subduction zones. The best places are a deep ocean- trench like the Mariana Trench in the pacific ocean.
Answer:
2 minutes or 120 seconds
Explanation:
The answer is 2 minutes or 120 seconds because 36 km is 36000 m and 36000 divided by 300 is 120, so the answer is 120 seconds, and converted to 2 minutes. Hope it helps!
Answer:
Electric force, 
Explanation:
It is given that,
Magnitude of electric field, 
Charge, 
The electric field is directed parallel to the positive y axis. We need to find the force on the charge particle. It is given by :
So, the electric force on the charge is 
. Hence, this is the required solution.
