Document Summary

The amount of heat (energy) per unit mass required to raise the temperature by one degree celsius . Gel inserts in technology, foot supports, pillows, helmets. Inside skull, there is cerebral spinal fluid to cushion brain. Ph of 4: [h+] = 1e-4 mol/l to 0. 0001 mol of hydrogen ions in a solution of 1 liter. Ph of 7: [h+] = 1e-7 mol/l to 0. 0000001 mol of hydrogen ions in a solution of 1 liter. Ph of 7 has less hydrogen ions than ph of 4. Ph > 7 = basic (less hydrogen ions) Ph < 7 = acidic (more hydrogen ions) Changing even a tenth in ph can have a huge affect on the body. Chemicals that can regulate ph change by accepting or donating extra h+ ions when needed. All cells have some common structures and functions. Membrane proteins that act as transporter or channel.
