Question

1. the mass of a sample is measured in grams, and its volume is measured in cubic centimeters. in what units would its density be reported? 36. look at table 3.6. circle the letter of the material that will sink in liquid water at 4°c. a. aluminum b. corn oil c. ice d. gasoline 37. the density of a substance generally decreases as its temperature increases. are there any exceptions to this statement? explain. 38. looking at figure 2 11 on page 81, is the blue - colored liquid more or less dense than the water? would the blue - colored liquid have a density greater than or less than 1? interpret data, page 81. looking at table 3 6, answer the questions in the book.

Explanation:

35.

Step1: Recall density formula

Density $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute units

Mass $m$ is in grams (g) and volume $V$ is in cubic - centimeters ($cm^{3}$). So density units are $\frac{g}{cm^{3}}$.

A substance sinks in water if its density is greater than the density of water at $4^{\circ}C$ ($1 g/cm^{3}$). Aluminum has a density greater than $1 g/cm^{3}$, while corn - oil, ice, and gasoline have densities less than $1 g/cm^{3}$.

Water is an exception. Water has a maximum density at $4^{\circ}C$. When the temperature of water is below $4^{\circ}C$, as the temperature increases, the density of water increases. When the temperature is above $4^{\circ}C$, the normal behavior (density decreases with temperature increase) occurs. This is due to the unique hydrogen - bonding structure of water molecules.

Answer:

$\frac{g}{cm^{3}}$
