Answer:
C. Research what has been done in the past to clean up oceanic oil
residue.
Explanation:
The engineer being an innovator would probably have to dig through the past to see what has been done before him and in what way his technology is addressing the problem. If sees that his invention is unique, he would get a patent for his invention and then proceed to design the device. If he does not do this, he might just waste his whole duplicating an invention already made.
Answer:
A change is called irreversible if it cannot be changed back again. For example you cannot change a cake back into its ingredients again. Irreversible changes are permanent.

Answer:
The temperature of the balloon is 46.34 K.
Explanation:
An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P * V = n * R * T
In this case:
- P= 0.76 atm
- V= 10 L
- n= 2 moles
- R= 0.082

- T= ?
Replacing:
0.76 atm* 10 L= 2 moles* 0.082
*T
Solving:

T= 46.34 K
