You have a balance that can measure mass to the nearest gram. Which measurement is written with the correct amount of precision?
A. 0.1 g
B. 11 g
C. 11.1 g
D. 11.12 g

B. 11 g

Explanation:

When we want to express a value in decimal number, we can do it in several ways.

For example, if something weighs 7.827 grams, we can write it as following:

- to the nearest gram (no decimal number): 8g

- to the nearest 0.1 grams (one decimal): 7.8g

- to the nearest 0.01 grams (two decimals): 7.83g

to the nearest 0.001 grams (three decimals: 7.827g

Basically, we simply round the number to the adequate decimals.

If we are asked to rouund a value to the nearest gram (or meter, second, centimeter etc.) we need to round it to a whole number, without decimals.

In this particular case, only answer B. meets the condition.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
