Acolorimeter 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. the readings of the second colorimeter aren’t reliable and can’t be used for the experiment.

is this a psat question, if so do not cheat try your best.

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
