General Fundamental Scientific Principles 3

Question 1

What is the relationship described by Ohm's Law?

Accepted Answer

Voltage equals current multiplied by resistance

Answer

Ohm's Law states V = IR, meaning voltage equals current (amperes) times resistance (ohms).

Question 2

Which organelle is responsible for producing ATP through cellular respiration?

Accepted Answer

Mitochondrion

Answer

Mitochondria generate most of the cell's ATP via oxidative phosphorylation during cellular respiration.

Question 3

According to the Second Law of Thermodynamics, what always increases in an isolated system?

Accepted Answer

Entropy

Answer

The Second Law states that entropy (disorder) of an isolated system tends to increase over time.

Question 4

What is the process by which a solid transforms directly into a gas without passing through a liquid phase?

Accepted Answer

Sublimation

Answer

Sublimation is the direct phase transition from solid to gas, as seen with dry ice (solid CO₂) at room temperature.

Question 5

Which scientist formulated the law of universal gravitation?

Accepted Answer

Isaac Newton

Answer

Isaac Newton formulated the law of universal gravitation in 1687, describing the attractive force between any two masses.
