Where did dry ice get its name?

Dry Ice is the common name for solid carbon dioxide (CO2). It gets this name because it does not melt into a liquid when heated; instead, it changes directly into a gas (a process known as sublimation).

How does dry ice kill?

Dry ice is carbon dioxide in its solid form, and it turns into gas when exposed to open air. The carbon dioxide can then displace oxygen in the air, which can cause difficulty breathing, loss of consciousness and death, according to The News Tribune.

Does dry ice kill bacteria?

“Since the bacteria removal rate is less than five log10 units, dry ice blasting cannot be recommended as a disinfection method, but it demonstrates efficient cleaning comparable to other conventional methods.
