Answer:
Density of the object = 1.67 g/ml (≅1.7 g/ml)
Explanation:
<u>Given:</u>
Mass of the object, M = 14.01 g
Initial volume of water in the cylinder, V1 = 25.2 ml
Volume of water after the object is placed in the cylinder, V2 = 33.6 ml
<u>To determine</u>
The density D of the object
<u>Explanation:</u>
Density (D) of a substance is the mass (M) occupied by the substance in a given volume (V) i.e.
In this case:
M = 14.01 g
The volume V of the substance = V2-V1 = 33.6-25.2 = 8.4 ml

Explanation: Boiling point is the temperature at which vapor pressure of the liquid becomes equal to atmospheric pressure.
Boiling point depends on the strength of inter molecular forces. The molecules of hydrocarbons are bonded through weak vanderwaal's forces. As the length of carbon chain increases, the surface area increases and thus the vanderwaal forces increases, thus more heat is to be supplied to break the bonds and thus there is an increase in the boiling point.
