Question

In an experiment, a substance at 300 C is taken in a beaker. It is heated until the temperature increases by 22.50 C. It is then cooled until the temperature decreases by 27.30c. What will be the final temperature of the substance?

Answer 1

Answer:

initial temperature = 300c

temperature after heated by 22.50 = 300+22.5=322.5

final temperature=322.5-27.30=295.2c
