I need help for these few homework questions:
1. The pH of 2 is how many times that of a pH of 4?
2. What property of water allows organisms to maintain a stable internal body temperature?
3. A base is the concentration of what type of ions?

2. Water absorbs heat. Thats why you sweat, when its hot, it cool you down, by absorbing the heat from your body
3. OH negative ions

(1) pH2=10 to the power of minus 2=0.02M-----pH4= 10 to the powerof minus 4=0.0004M----at pH2 there will be 50 times(0.O2/0.0004=50) the amount of Hydrogen ions than pH4.
(2) Water has "Latent Heat of Vapourisation"---Without change in temperature ,water can take a reasonable amount of heat.Its thermal capaacity will increase but Temperature will remain constant.
(3)According to Bronsted-Lowry concept a base has a broad meaning.However it can be said OH ions will increase
