What is the difference between the total number of California condors in 1982 and the total population in 2016?

The California Condor is on the verge of extinction. There were three individuals, all males, known to be living free in late 1986. That was a drop from fifteen wild birds (including five breeding pairs) known to have been present in 1984. Twenty-one condors were also alive in captivity toward the end of 1986.

Explanation:

The new volume is 114.1 L

Explanation:

Step 1: Data given

Volume of the helium balloon = 69.5 L

The atmosphere pressure is 101.3 kPa

The pressure decreases to 61.7 kPa

Step 2: Calculate the new volume

P1*V1 = P2*V2

⇒with P1 = the atmosphere pressure is 101.3 kPa

⇒with V1 = the initial volume = of the helium balloon = 69.5 L

⇒with P2 = the decreased pressure = 61.7 kPa

⇒with V2 = the new volume = TO BE DETERMINED

101.3 kPa * 69.5 L = 61.7 kPa *  V2

V2 = (101.3 kPA * 69.5 L ) / 61.7 kPa

V2 = 114.1 L

The new volume is 114.1 L
