Un tren se mueve con velocidad de 36 km/h y en 1 min aumenta progresivamente su velocidad hasta llegar a 72 km/h. Calcular la aceleración del tren en m/s 2 .

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
