What happens to the size of molecules and what happens to the total mass of the sample when heat is applied to an ice cube in a closed container has to be explained. Concept Introduction : Melting is a process in which solid transforms into liquid and boiling is a process in which liquid transforms into vapor phase. For both these process to happen heat has to be applied to the substance under consideration. The size of the atoms or molecule of a substance does not change when heat is applied. The volume alone increases if heat is supplied. Kinetic energy of the gas molecules also increases. To Explain: When heat is applied to an ice cube, what happens to size of the molecules and what happens to the total mass of the sample has to be explained.

The emission data in cps displayed in Table 1 is reported to two decimal places by the
chemist. However, the instrument output is shown in Table 2.

Did the chemist make the correct choice in how they choose to display the data up in Table
1? Choose the best explanation from the choices below.
No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated.
Doing so would eliminate significant information.
No. Since the instrument calculates 5 decimal places for the standard, all of the values should be
limited to the same number. The other decimal places are not significant for the blank and unknown
sample.
Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware
can report values to 2 decimal places, and this establishes our number of significant figures.
Yes. Instrumental data…
