A certain type of ship has two tanks in its engine. Each tank contains a different type of fuel. When the engine turns on, the same amount of energy is transferred out of both fuels as shown in the diagram below. Why did fuel 1 change phase, but fuel 2 stayed the same? Explain what happened to the molecules of both fuels.
PLEASE HELP ASAP!!!!!!
Answers
Answer:
Fuel 1 changed phase because the energy drawn from it dropped its temperature below the transitional temperature that causes a phase change, fuel 2 still has its temperature well above the transitional temperature required to change phase
Explanation:
For a substance to change phase, a transitional temperature has to be reached. This is because, the temperature of substances generally indicates the average kinetic energy of its molecules. An increase in energy input to the system will result in a change to a more mobile phase like from solid to a liquid state or from a liquid state to a gaseous state state, while taking energy from the system will cause a transition to a less mobile phase like gas to liquid or liquid to solid state.
Answer: Based on attraction
Explanation:
Fuel 1 changes the phase because it contains a stronger attraction molecules type of fuel. Fuel 1 before turns on (transfer out), the molecules are moving away from each other, and after they are moving around each other.
Fuel 2 doesn't change the phase because it contains weaker attraction molecules type of fuel. Fuel 2 before turns on (transfer out), the molecules are moving away from each other, and no movement next
