a colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. in an experiment, a scientist used two colorimeters and noted the readings. the first colorimeter showed consistent readings that were five points lower than the actual reading. the second colorimeter provided readings that were the same as the actual reading. which two statements are implications of these readings?
the first colorimeter is reliable but not valid.
the second colorimeter is valid and reliable.
both the colorimeters are reliable and valid.
the readings of the first colorimeter can be used without repeating the experiment.
