Define each statement in terms of the accuracy and precision its situation shows. True values:

* Boiling Point = 373K

* Freezing Point = 273 K

* Hydrogen mass= 1.00794 amu

1) I measure boiling water to have a temperature of 200 K. I get the same result each time.

2) I measure ice water four times, and get results of 5 K, 234 K, 700 K, and 273 K.

3) I measure a 2 kg weight three times, and get 3.60 kg, 3.45kg, and 3.50 kg for results.

4) I measure the mass of an atom of hydrogen 3 times, and receive the following results: 1.008 amu, 1.007 amu, & 1.009 amu.

what is the average time it took the car to travel 0.25 meters?

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

i think it's letter a.
