Which statement defines the temperature of a sample of matter?
stepan [7]
Temperature is a measure of the average kinetic energy of the particles in the sample. This is the statement that defines the temperature of a sample of matter.

The temperature of a system is defined simply as the average energy of microscopic motions of a single particle in the system per degree of freedom.

The microscopic motions in a solid matter is the principal vibrations of the constituent atoms about their sites. In an ideal monoatomic gas, the microscopic motions are the translational motions of the constituent gas particles. In multiatomic gases, aside from translational motions, vibrational and rotational motions are included in the microscopic motions.

What is the pH of a 0.50 M C6H5NH3Br solution? KbC6H5NH2 = 3.9x10-10 (R = 2.45)
masya89 [10]

Answer:

It commonly ranges between 0 and 14, but can go beyond these values if sufficiently acidic/basic. pH is logarithmically and inversely related to the concentration of hydrogen ions in a solution. The pH to H + formula that represents this relation is: The solution is acidic if its pH is less than 7.

Compared with surface currents, deep currents are a. colder and less dense. c. warmer and denser. b. warmer and less dense. d. c
Katyanochek1 [597]

The correct answer is option d, that is, colder and denser.  

The surface currents refer to the currents at the surface of the water, to a few hundred meters deep, while deep currents refer to the currents when the density increases to a greater extent.  

The surface current takes place close to the surface and move horizontally. This kind of currents are caused by global winds, an example of surface current is Gulf Stream. On the other hand, deep current takes place in the ocean and is affected by the density of water, temperature, and salinity. An example is Antarctica Bottom Water. In comparison to surface currents, deep currents are colder and denser.
