BIOCHEMISTRY EXAM PREDICTION
QUESTIONS
weaker
the higher the dielectric constant, the (stronger/weaker) the
interaction between charges
stronger
alcohol causes dehydration, which leads to (stronger/weaker)
charges in the body

high heat of vaporization
what property of water helps prevent dehydration?
high
does water have a high or low dielectric constant?
