Divide 68.793 by 1000, and then round that number to the nearest thousandth.

In order to divide 68.793 by 1000, we can simply move the decimal to the left because the number will decrease in size when this operation is performed. Because there are three zeros in 1000, we will move the decimal point three spaces to the left, leaving us with the number 0.068793. Now, we must round this number to the nearest thousandth. The spaces go in order from tenth, hundredth, thousandth. This means, we will round to the third number from the decimal, leaving us with a final answer of 0.069. We rounded the final number to a 9 due to the 7 that followed the eight being higher than 4.

If you fill a glass with both liquid H2O and solid H2O (water and ice), what will happen as the solid H2O undergoes fusion and becomes liquid H2O due to the room temperature?

We know that the properties of H2O make it expand as it transitions from a liquid state to a solid state. The molecules move much slower when water freezes, but they sit in a position of increased surface area. When H2O is in a liquid state, the molecules move faster and move around more, but the molecules are packed more tightly together. Because of this, as the ice melts, the level of H2O in the glass will slightly decrease, and will hit its lowest point when all of the ice has melted.
