la longitud de un cable de aluminio es de 30 m a 20 C. Sabiendo que el cable es calentado hasta 60 C y que el coeficiente de dilatacion lineal del aluminio es de 24x 10 -51 C, determina la longitud final del cable y su dilatacion.​

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
