Matter is all the “stuff” that exists in the universe. It has both mass and volume. Mass measures the amount of matter in a substance or an object. The basic SI unit for mass is the kilogram (kg). Volume measures the amount of space that a substance or an object takes up.
Answer:
When we engage in physical exercises and we sweat the body tries to return to its optimal temperature, as sweat evaporates from the skin, heat is removed from the body, but the body also loses body fluids, therefore one needs to take lot of fluids during exercise as this will help replace the fluid that is lost during sweat.
The pH of blood if pco2 drops to 35.0 mmHg is 7.459
The pH of the blood can be calculated using the Henderson- Hasselbalch equation, which explains the relationship between acid dissociation constant pKa and pH in biological and chemical systems.
pH = pK + log ( HCO3- / ( 0.03 * PCO2 ) )
pK is 6.1 for the bicarbonate buffer system.
HCO3- = 24mm
PCO2 = 35.0 mmhg
pH = 6.1 + log ( 24 / 0.03 * 35.0 )
= 6.1 + log ( 24 / 1.05 )
= 6.1 + log 22.8571
= 6.1 + 1.3590
= 7.459
Hence, the pH of blood is 7.459
