V = I × R
Voltage - Current - Resistance
if the resistance is constant, increases in voltage cause increases in current flow. |

Boil - Temperature is constant
pressure up > volume down
P1V1 = P2V2
TEMPERATURE HAS TO BE IN KELVIN!!!! |

Constant is Pressure
T up = V up
V1 / T1 = V2 / T2
TEMPERATURE HAS TO BE IN KELVIN!!!! |
