Método del primer ejercicio
1.- Lo primero que hicimos es buscar el agua a temperatura ambiente y la medimos con el termómetro, después ponemos agua en una olla para calentarla y medimos su temperatura luego de esto ya tenemos la temperatura de ambas parte
Agua temperatura ambiente 35 C
Agua caliente temperatura 42 C
Una vez ya identificadas procedemos a echarlas en el calorímetro esperando un minuto para medir su temperatura que se llamara teq, una vez pasado el minuto medimos su temperatura con el termómetro que se utilizo anterior mente
Temperatura de ambas 37 C
Como nos están pidiendo pasaremos a calcular la temperatura teorica de nuestra mezcla utilizando la formula que se nos da
Calculamos y nos da por resultado 500cal y 300cal
Para terminar calculamos el valor teorico de la temperatura de equilibrio Teq con el obtenido experimentalmente.
Concluyendo con el resultado de Eabsoluto= 25–37=-12
Solved

Ответ:
When we are heating a liquid, it temperature increases till a certain point. At this point, even after providing further heat, the temperature does not increase but the state of matter starts to change from liquid to gas. The temperature of the substance does not change till all of the liquid boils off into gaseous form. Hence, this temperature (135°C) is known as boiling point. The point at which the entire liquid gets converted into gaseous form is known as boiling point.
