- 3 What causes snow? Why doesn't rain just turn into ice?
- 4 OK, Stephen really knows his stuff on this branch of physics... he's studied in detail.
- 5 Why is the density of solid water lower than liquid water?
- 6 Is there any other molecule that also expands when it is solid?
- 7 Why is the density of solid water lower than liquid water?
- 8 For ice skating, the ice melts at the contact of your blade so there is a small layer of liquid water due to friction, and hence it skates.
- 9 But you also can push and speed up on ice while skating, so an increase in the friction must have happened?
- 10 Apparently, gecko feet exhibit Casimir-like effects.
- 11 Stephen, if I may make a suggestion: you need a blackboard or whiteboard behind you for the explanations.
- 12 Is air a molecule? What is air?
- 13 Can you measure the absorption of CO2 by plants with this device?
