What scale rates petrol against a known mixture of iso-octane and heptane?
- A.
Octane
- B.
Neuron
- C.
Beaufort
- D.
Richter
Correct Answer
A. OctaneExplanation
The scale that rates petrol (gasoline) against a known mixture of iso-octane and heptane is called the octane rating scale. This scale measures the fuel's resistance to knocking or premature ignition in an engine. A higher octane rating indicates that the fuel is more resistant to knocking, which is desirable in high-performance or high-compression engines.Rate this question:

What stage of the scientific method tests a hypothesis?
- A.
Experimentation
- B.
Characterization
- C.
Observation
- D.
Conclusion
Correct Answer
A. ExperimentationExplanation
The stage of the scientific method that tests a hypothesis is the experimentation stage.

An atom is the smallest possible unit of what?
- A.
A Cell
- B.
A Proton
- C.
A Compound
- D.
An Element
Correct Answer
D. An ElementExplanation
An atom is the smallest fundamental unit of an element that retains the chemical properties of that element. Atoms consist of a nucleus composed of protons and neutrons, surrounded by a cloud of electrons. Protons have a positive charge, neutrons have no charge (they are neutral), and electrons have a negative charge. The number of protons in the nucleus determines the element's atomic number, which uniquely identifies the element.Rate this question:
