Resumen
En este trabajo se realiza la propuesta de un laboratorio para determinar las variables físicas que caracterizan al agua, como son el olor, el color, la temperatura, la densidad, la turbidez, la conductividad, el pH, la tensión superficial y el índice de refracción, con el objetivo de estipular la calidad del agua. Para ello se explican las vías y los métodos para el hallazgo de esas magnitudes y luego se escogen tres muestras diferentes, independientes entre ellas y se encuentran los valores de las variables físicas, para cada muestra, pudiendo compararlos entre sí y concluyendo según el test estadístico de Kruskal-Wallis que existen diferencias significativas entre las variables para cada muestra. Por último y tomando como apoyo la Norma Cubana del Agua 1021:2014, se proponen normas para el agua.

Finally, and taking as support the Cuban Water Standard 1021: 2014, water standards are proposed.
