as the temperature of a substance increases , the molecules in that substance will move faster / farther apart
temperature_per_distance_ratio is two_dimensional_quantity. advection is not temperature_change. heat is not temperature. advection is temperature_change. temperature is not one_dimensional_quantity. increase_in_temperature is not temperature_fluctuation. friction has effect_of_increasing_temperature temperature_per_distance_ratio is not multi_dimensional_quantity. temperature_per_distance_ratio is not two_dimensional_quantity. friction has not effect_of_increasing_temperature
