Q

pH level effects in vapes & cigs

A

Bases (high pH) cause more absorption & feels harder/scratchy; conjugate base form of nicotine would dominate
Acids (low pH) cause less absorption & feels smoother; pronated form of nicotine dominates

Q

Temperature

A

Measure of the average amount of energy of motion, or kinetic energy, a system contains

17
Q

Purpose of Kelvin scale

A

There exists a minimum possible temperature called absolute zero. Kelvin’s scale is set so that 0 K is absolute zero.

18
Q

Hyperthermia

A

Inability of the body to regulate heat

Caused by fever(infection), heat stroke, thyroid disorders, heart attack, or traumatic injury

Treatment = hydration, cool bath, or analgesics

19
Q

Hypothermia

A

Exposure to cold environments, body has problems producing heat

Caused by diabetes, infection, and thyroid dysfunction

Treatment = remove wet clothes, warm clothes, & movement

20
Q

Cryogenics

A

Branch of physics that incorporates the production and effects of substances at temperatures ranging between -150 C to -273 C. Cryogenic science began with cooling gaseous oxygen. Changing the state of gases enables it to be transported easier.

21
Q

Liquid nitrogen vs dry ice

A

Liquid nitrogen = cryogenic, used in dermatology

Dry ice = solid carbon dioxide, much warmer, not considered a cryogenic
