D is the answer I believe.
The statement that best explains why heating a liquid affects its viscosity is that "The molecules move faster at higher temperatures and overcome attractions more easily."<span>. Remember that viscosity is a physical property of the fluids that measure the resistance (opposition) to flow and it, generally decreases, as the temperature increases and the intermolecular force decrease.</span>
Answer:
Pressure of the trapped gas and the pressure on the outside on the piston are the same.
Explanation:
When the piston is at rest, then it exist a mechanical equilibrium, that is to say, that pressure of the trapped gas is equal to the pressure on the outside of the piston.
Similar - Both are organic compounds and fossil fuels
Different - natural gas is made up of lighter organic compounds than petrolium
