A fluid is a medium that has a defined mass and volume, but no fixed shape, at a constant temperature and pressure. This may include gases, liquids, plasmas, and to some extent plastic solids. A fluid can flow and deform, preventing it from carrying loads in a static equilibrium. A fluid is always compressible and internal frictional forces always occur due to the viscosity of the fluid.

If the pH of a solution is 5, what is the hydrogen ion concentration?

Gnoma [55]

Yo sup??

We know that

pH=-log[H+]

[H+]=10^(-pH)

pH=5

therefore

[H+]=10^(-5)

The medium is acidic

Hope this helps.

3. Gasoline, coal, batteries, and logs all have chemical energy. When they burn that chemical energy will be transformed into en

Arturiano [62]

Answer:

Thermal energy

Explanation:

When gasoline, coal, batteries and logs are all burn they transform chemical energy to thermal energy.

The chemical energy is the energy held between chemical chains and bonds within an atom.

When they combust, they release thermal energy
Chemical energy is a potential energy.
The thermal energy is a kinetic energy
It increase the average motion of the particles in the medium
The breaking bond when produces heat which is a form of thermal energy.
