A weather balloon is inflated to a volume of 27.2 l at a pressure of 753 mmhg and a temperature of 30.9 ∘c. the balloon rises in
gayaneshka [121]

By idea gas equation we can say

PV = nRT

here P = pressure

V = volume

n = number of moles

R = Avagadro gas constant

T = temperature

So from above expression you can see that for constant number of moleswe can say

\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}

\frac{753*27.2}{273+30.9} = \frac{395*V_2}{273-15.9}

67.4 = 1.54*V_2

V_2 = 43.9 L

So finally the volume will be 43.9 L

Why is technology important for making observations
GrogVix [38]

Answer:

Technology allows us to observe things that cannot be sensed or observed by the limits of our natural senses. For example, technology allowed us to observe the first cells, without the invention of the microscope, we would have not been able to discover cells. This is how many of our theories, laws and other scientific facts were discovered.

Not only that, when it comes to objective measurements or observations, technology can be more precise.
