0°C to 40°C is double the temperature of 0°C to 20°C. Does this mean you have twice the amount of kinetic energy in your system?
A) Yes. If the temperature doubles then the kinetic energy must also double. They are directly related.
B) No. Temperature is related to the heat energy of the gas particles, not the kinetic energy of the gas particles.
C) No. Temperature is related to the kinetic energy of the gas particles but must be in relationship to the kelvin scale.
