Excellent science quiz, really taxed my knowledge and memory from high school and college ... which was decades ago. I'm very happy with my 88/100 score.

[danielrutschman]

If these questions are too difficult for most people then most schools are doing a very poor job of educating.

I'm quite happy with my 90/100

There are only three classical states of matter, plasma is not a classical one.

I disagree with #36. Centrifugal force is actually a fictitious force. In all cases, the force is centripetal force. It's not the opposite. It's just the only real force.

Great quiz! But I'm not sure about question 97 (expanding gas). If the gas in question is an ideal gas, it is true that the temperature remains the same, but for other gases, e.g. those described by the Van der Waals equation, the internal energy also depends on the volume of the gas. If the gas expands in a vacuum, the internal energy remains constant (there is no work or heat transfer). For the Van der Waals gas, the only way to keep the energy constant as it expands is to lower its temperature.

It's eerie how the red line moves faster on the questions I don't know.

Nice quiz.
91.
As others have noted (maybe, probably):
* Centrifugal forces are "pseudo forces" and are not real. Centripetal just means inward acting. It's an ill-posed question.
* Only ideal gases have constant temp on free expansion.
* Cellulose has the same energy density as starch (both being polysaccharides), if an animal has the enzymes to digest it.
* Plasma was added as a state after the classical science period.

Strictly speaking, more heavy water is used for drinking. 0.015% in natural water or .15 grams per liter. I expect more is consumed by drinking than used in nuclear reactors.

88/100 which is not bad for an old artist whose last science lesson was 1962!!! Enjoyed that, but must admit to some inspired guesses. 🇬🇧👍

I am 75 and still apparently remembering most of my high school science because I missed only three, one of them being that the largest eyes belong to the ostrich; I concluded the elephant!

[jimmartin]

I always feel smarter after watching. Sometimes it's good enough to say I understand the question, even if I don't know the answer.😛

The double slit experiment for light proves that light is a wave not both. It's the photo electric effect that proves that light is a particle.

[laszlovida]

90/100 here - 4 lack of scientific knowledge - 6 lack of language knowledge :D (I'm not native english, but i'm proud, that understood most of the questions)

[patmcgillhastings]

solid, liquid, gas and plasma....height, length, width, and time. Missed 4 of the questions. I really enjoy the science quizzes. Thanks Ben, for the best quizzes on youtube. You are meticulous in your presentation and correctness of answers. Please know that all your time and hard work does not go unnoticed and is always appreciated.😊👍

As a total non-science person, I figured I get about 10% right. I did better than I thought by just being alive and somewhat informed. I got around 70%. Yay!

[rossd]

I scored 91/100. If that represents a very good score, I would say our public schools are doing a poor job in educating students.

[johnharris]

94% ! Didn't seem to help me much throughout life. I'm 71. It was more who you know and who you blow!

[dadananda]

Hmm... The double slit experiment shows that light behaves as waves. If particles are used instead of light, you also get an interference pattern which proves that particles can behave as waves. But the double slit experiment does NOT show that photons behave as particles - as is implied.

[gunnargronvall]

I got 97%, I am an geologist with astronomy as a hobby .

There are gyros in smartphones, there is a magnetic sensor and a series of accelerometers that perform the function of sensing angles similar to the way a gyro would.
