Explanation:

Larger networks of streams, lakes, rivers etc describe the river system as there are all part of a river's network.

Rivers, streams, and ground water move across the land and thus they contribute to the river system. Whereas a lake is defined as a large area of water which is surrounded by land and does not really contribute to river system.

Therefore, we can conclude that groundwater, rivers, and streams are the water sources that contribute to a river system.

A steel tank contains carbon dioxide at a pressure of 13.0 atm when the temperature is 34oC. What will be the internal gas press

morpeh [17]

Answer:

D. 15.8atm

Explanation:

Given parameters:

Initial pressure = 13atm

Initial temperature = 34°C = 34 + 273 = 307K

Final temperature = 100°C = 100 + 273 = 373K

Unknown:

Final pressure = ?

Solution:

To solve this problem, we apply a derivation of the combined gas law taking the volume as a constant.

The expression is shown mathematically below;

$\frac{P_{1} }{T_{1} }$ = $\frac{P_{2} }{T_{2} }$

P and T pressure and temperature values

1 and 2 are initial and final states

Insert the parameters and solve for T₂;

$\frac{13}{307}$ = $\frac{P_{2} }{373}$

P₂ = 15.8atm
