A bicycle tire is filled with air to a pressure of 720 torr at a temperature of 19 degrees Celsius. Riding the bike on asphalt on a hot day increases the temperature of the tire to 58 degrees Celsius.
How might temperature changes in the human body have an impact on human health? (Use an example to help illustrate your understanding). The human body goes through various temperature changes during a single day.
Water and toluene are very good recrystallization solvents. Why is it not useful to use these solvents for a ‘quick' recrystallization?
