The correct statements are that the first calorimeter is reliable but not valid, and the second calorimeter is valid and reliable.
Explanation:
The first calorimeter is reliable as the reading demonstrated by it is similar when each time the experiment is performed, however, the result attained is not correct, though it is reliable. On the other hand, the second calorimeter is both reliable and valid, as it is demonstrating the accurate results from time to time. This is valid as it is providing a similar result as that of the original readings.
