<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
Precision refers to the closeness of two or more measurements to each other.
For Example: If you weigh a given substance five times and you get 3.2 kg each time. Then the measurement is very precise.
Accuracy refers to the closeness of a measured value to a standard or known value.
For Example: If the mass of a substance is 32 kg and one person weighed 31 kg and another person weighed 29 kg. Then, the weight measured by first person is more accurate.
According to the question:
Mass weighed by Mary = 10.00 g
Mass weighed by Tommy = 10 g
As, mass weighed by Mary is reported upto 2 decimal places. Thus, it is more precise.
Hence, the correct answer is Option C.

Answer:
Water obeys the Law of Conservation of Matter despite changing into different forms because when water does change forms, the amount of water stays the same. The Law of Conservation of Matter states that before matter undergoes change, be it through physical or chemical means, the same amount of matter exists. Matter cannot be created nor destroyed during the change. When water changes from a liquid to a gas the molecules change form by breaking the bonds that held them in a liquid state, but this does not create new matter. The molecules can now move more freely but are still the same as they were before. Same goes with the change from a liquid to a solid. The molecules slow down and become more compact, forming a solid. Though again, this does not create new matter nor destroy existing matter, therefore obeying the Law of Conservation of Matter.
