Properties of ice
Water freezes at this temperature (Kelvin).
What is 273K?
The temperature of liquid nitrogen (Kelvin).
What is 77K?
Antarctic water remains liquid below 0 C because it contains this.
What is salt?
This what dry ice is made of.
What is CO2?
The average kinetic energy of particles when a substance is cooled.
What is decreases?
Ice floats in water because of this reason.
What is the density of the crystal lattice?
The temperature of liquid helium (Kelvin).
What is 4K?
Sea ice contains tiny pockets of this concentrated salty liquid.
What is brine?
This insulated container is used to store liquid nitrogen while minimizing heat transfer.
What is a dewar?
This property of molecules ceases at 0K.
What is atomic motion?
What is freezing point depression?
This is the color of liquid oxygen.
What is blue?
In Antarctica's dry valleys, ice can skip the liquid phase and turn straight into vapor. This process is...
What is sublimation?
This common instrument is kept cold by two layers of cryogenic liquid (one layer of liquid He, one layer of liquid N2).
What is NMR?
This thermodynamic lay states that heat naturally flows from hot to cold.
What is the second law of thermodynamics?
Frost forms on a cold window when water vapor turns directly into ice (skipping the liquid phase).
What is deposition?
This is the coldest planet in our solar system (49 K).
What is uranus?
Cold polar clouds help activate this halogen (released from CFCs). When spring sunlight returns, its radicals help destroy ozone.
What is chlorine?
This temperature is the limit for something to be considered cryogenic.
What is 123 K or -150 C?
At constant pressure, when water is at its freezing point, this property also remains constant.
What is temperature?
Ice forms in two crystal structures. The geometric shapes are...
What is hexagonal and cubic?
This is the lowest Kelvin temperature recorded.
What is 38 picokelvin?
Antarctic fish make these ice-binding biological molecules to stop ice crystals from forming in their bodies (Hint: nature's version of a car's coolant).
What are antifreeze proteins?
This instrument is used to separate and collect gases such as N2, O2, and Ar based on their different boiling points at extremely low temperatures.
What is a cryogenic distillation column?
What is adiabatic?
