Answer:
The internal combustion engine in the car converts the potential chemical energy in gasoline and oxygen into thermal energy which is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy) by causing the pressure and performing the work on the pistons.
Explanation:
Answer:
C. Releases less carbon dioxide
Explanation:
since geothermal steams are directly from earths surface they do not have carbon dioxide therefore they can be used to rotate turbines ultimately generating electricity.
Answer:
20.5 torr
Explanation:
Given parameters:
Volume of tank = 15L
Pressure of tank = 8.2 x 10⁴torr
Volume of empty chamber = 6.0 x 10⁴L
Unknown:
New pressure of the gas in this chamber = ?
Solution:
To solve this problem, a good knowledge of the gas law will suffice here. Since pressure and volume relationships are under consideration, the Boyle's law is the proper gas law to apply.
Boyle's law states that "at constant temperature, the volume of fixed mass of gas is inversely proportional to the pressure of the gas".
Mathematically;
(Pressure x volume) of tank = (Pressure x volume ) of empty chamber
15 x 8.2 x 10⁴ = Pressure of empty chamber x 6 x 10⁴
Pressure of empty chamber = 20.5 torr
It is 3 moles. Don't doubt urself
