The densities in grams per cubic centimeter of various sub- stances are listed below.
for each density, tell whether the substance is most likely to be a gas, a liquid, or a solid.
a. 0.0015
b. 10.0
c. 0.7
d. 1.1
e. lo"4

a. Solid

d. Liquid

c. Gas

Explanation:

In the solid-state, we will have a larger amount of mass in a small amount of volume. If we remember the density equation:

Mass and density are directly proportional, therefore if we have more mass we will have more density. So, the highest density value most is solid-state. For the liquid state, we will have less mass in the small value, thus the density value that follows would be d. Finally, for the gas state, we will have more volume than mass, so the density value can be lower than 1, the value the follows d. is c. The gas state.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
