Aballoon initially has a volume of 45 l at sea level, where temperature is 25∘c and the pressure is 1.0 atm. it rises to an elevation of 2.0 km, where the temperature is 5.0∘c and the pressure is 0.78 atm. what is the balloon's volume at this height?

The answer to your question is Volume = 11.54 liters

Step-by-step explanation:

Data

Initial volume = V1 = 45 l

Temperature 1 = T1 = 25°C

Pressure 1 = P1 = 1 atm

Temperature 2 = T2 = 5 °C

Pressure 2 = P2 = 0.78 atm

Volume 2 = V2 = ?

Process

Use the combined law of gases to solve it

Solve for V2

Substitution

Simplification

Result

                  V2 = 11.54 liters

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
