The vapor pressure of dichloromethane, CH2Cl2, at 0 C is 134 mmHg. The normal boiling point of dichloromethane is 40. Calculate its molar heat of vaporization
Biological muscle cells can be thought of as nanometres that utilize the chemical energy of ATP to produce mechanical work. Measurements show that the active proteins within a muscle cell (such as myosin and act in) can produce a force of about 7.5 p..
