What Did Periodic Table of Videos Demonstrate in Its BBC Radio Nottingham Interview?

TL;DR

Periodic Table of Videos demonstrated how extreme cold and expanding gas produce striking effects using liquid nitrogen, a helium balloon, dry ice, and film canisters. Liquid nitrogen was identified as −196°C and made the balloon shrink, while solid carbon dioxide changed directly from solid to gas and caused a canister to pop. Read on for the science behind each radio experiment and the team’s unexpected public recognition.

Questions & Answers

Q: What experiments did Periodic Table of Videos demonstrate on BBC Radio Nottingham?

Dr Pete Licence and Samantha Tang brought liquid nitrogen, a helium-filled balloon, dry ice, and old film canisters from their lab. They demonstrated evaporating nitrogen, a shrinking balloon, and a canister popping as carbon dioxide gas expanded inside it.

Q: Who appeared in the BBC Radio Nottingham interview?

Dr Pete Licence and Samantha Tang from the University of Nottingham joined the BBC Radio Nottingham breakfast show. They discussed and demonstrated experiments previously featured by Periodic Table of Videos.

Q: How cold was the liquid nitrogen used in the demonstration?

The liquid nitrogen was described as being −196°C. When splashed around, it evaporated and produced nitrogen gas.

Q: Why did the balloon shrink when liquid nitrogen was poured over it?

The liquid nitrogen cooled the balloon and its contents, causing the balloon to shrink. The speakers identified helium as the gas inside the balloon.

Q: What happens to dry ice when it is left out?

The solid carbon dioxide goes directly from a solid to a gas. Unlike ordinary ice, it does not melt into a puddle of water.

Q: Why did the film canister explode?

Solid carbon dioxide inside the film canister changed into gas. As that gas expanded inside the closed canister, the pressure caused the canister to pop.

Q: What is the purpose of the Periodic Table of Videos project?

The project explains what the periodic table is about and what the element symbols encountered in chemistry lessons actually do. Its demonstrations include questions such as why glow sticks fluoresce and why some compounds explode while others do not.

Q: How widely were the Periodic Table of Videos scientists recognized?

The team said they were noticed in the street and while traveling around the country. Dr Pete Licence also recalled being recognized while walking along the seafront in Sydney after returning from Australia earlier that year.

Summary & Key Takeaways

• Nottingham scientists showcase experiments with liquid nitrogen and solid carbon dioxide.

• They illustrate the properties of elements on the periodic table through engaging demonstrations.

• The public reception of their educational content has been positive and engaging.
