Hello itsbabyrene99!
The answer to your question is 800 cm^3.
.
V = s^3
V = (20cm)^3
V = 800 cm^3
:)
It is the symbol used to represent nano meters.
Hope This Helps You!
Good Luck Studying :)
Is there a specific topic you're talking about?
If this is about climate change:
Over the last century. the average surface temperature of the Earth has increased by 1.0°F. The eleven warmest years this century have occurred since 1980, with 1995 the warmest on record. The higher latitudes have warmed more than the equatorial regions.
I hope you found this helpful! :)
Answer:
The new volume of the balloon will be 6046.28 L
Explanation:
Initial pressure (P1) = 99 kpa
initial volume (V1) = 3000 L
Initial temperature = 39 C = 39 + 273 = 312 K
Final pressure (P2) = 45.5 kpa
Final temperature = 16 C = 16 +273 = 289K
Final volume = ????
To calculate the final volume using the general gas equation
P1 V1 / T1 = P2 V2 / T2
make V2 the subject of the formular
V2 = 99000 ×3000× 289 / 45500×312
V2 = 85833000 /14196
V2 = 6046.28 litres
