Answer:
The final temperature is 30°C
Explanation:
The final temperature remains constant, the final temperature will be 30°C, because this is an isolated system, this system can exchange neither energy nor matter with the surrounding.
In this exercise we have to use the knowledge of thermal equilibrium, in this way we will be able to find the value of the final temperature, as:
The final temperature will be 40 degrees.
Thermal equilibrium is the situation in which two or more bodies are at the same temperature after heat transfer. When the bodies in the figure are at the same temperature, they are in thermal equilibrium.
using the information given that the system has an initial temperature of 30 degrees and one of the instruments is at 70 degrees, we find that:
