Acolorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. in an experiment, a scientist used two calorimeters 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 precise, but it is not accurate. It seems to have a zero error of -5.
We can conclude its precision because the readings are closely grouped, but its lack of accuracy is due to its variation from the actual value. Moreover, the variation is consistently of 5 points lower than the actual value, so its zero error may be -5.

The second colorimeter may be referred to as being accurate.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
