Show that the heat energy change, Q, to raise the temperature of 100 cm3 of water by 30 °C is approximately 13 kJ. [mass of 1.0 cm3 of
water = 1.0 g] [c for water = 4.2 J/g/°C] *

Qrepresents joules in the formula

Each calcium ion has a charge of +2, which can also be written as ca2+. if those ions move out of the neuron and no other ions are moving, the neuron would lose the positive charge associated with those ions and become more negatively charged.
