Answer:
2.10L
Explanation:
Given data
V1= 2.5L
T1= 275K
P1= 2.1atm
P2= 2.7 atm
T2= 298K
V2= ???
Let us apply the gas equation
P1V1/T1= P2V2/T2
substitute into the expression we have
2.1*2.5/275= 2.7*V2/298
5.25/275= 2.7*V2/298
Cross multiply
275*2.7V2= 298*5.25
742.5V2= 1564.5
V2= 1564.5/742.5
V2= 2.10L
Hence the final volume is 2.10L
Earth pulls it downward to the gravitational force
Explanation:
Distance travelled (d) = 56 metres
Time taken (t) = 7 seconds
velocity of the object (V)
= d / t
= 56 / 7
= 8 m/s
The velocity of the object is 8 m/s.
Hope it will help :)
