Answers below are taken from the article’s stored facts, so they match what the student read.

1. When was Heike Kamerlingh Onnes born?September 21, 1853
2. Where was Heike Kamerlingh Onnes born?Groningen, Netherlands
3. What is Heike Kamerlingh Onnes known for?Pioneering work in cryogenics, liquefaction of helium, and discovery of superconductivity
4. What is the career?Professor of Experimental Physics at Leiden University from 1882 to 1923
5. What did Heike Kamerlingh Onnes discover about electricity?He found that at very cold temperatures, mercury's electrical resistance disappears, meaning electricity can flow forever without losing energy.
6. How did Heike Kamerlingh Onnes make things super cold?He built special cooling machines and used them to liquefy gases like helium, reaching about 4.2 Kelvin.

Cryogenics: The branch of physics that studies the production and effects of very low temperatures.
Superconductivity: A phenomenon where certain materials exhibit zero electrical resistance below a critical temperature.
Absolute Zero: The theoretical lowest possible temperature, approximately -273.15 degrees Celsius or 0 Kelvin, where molecular motion ceases.
Electrical Resistance: The opposition to the flow of electric current, which causes energy loss as heat.
