There are three methods of heat transfer
They are located in the U.S.A
Answer: The density of the liquid is 
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of the unknown liquid = 938 grams
Volume of the unknown liquid =
Putting in the values we get:
Thus the density of the liquid is
and the liquid is dimethyl sulfoxide.
Answer:
a. changes with temperature.
Explanation:
Hello there!
In this case, according to the thermodynamic definition of the equilibrium constant in terms of the Gibbs free energy of reaction and the temperature of the system:

It is possible to figure out that the equilibrium constant varies as temperature does, not only on the aforementioned definition, but also in the Gibbs free energy as it is also temperature-dependent. Therefore, the appropriate answer is a. changes with temperature.
