<span>the piston should be in the upmost position to allow room for material to expand, thus be in vapor state, when a gas is compressed, it liquefies, and when dealing with a piston, much like in an auto combustion engine, the piston moves up and allows oxygen to mix with vapor and explode, thus powering further movement of pistons.</span>

If the object on the right gained mass so that it had as much mass as the
Viefleur [7K]

A) It would increase.

Explanation:

The gravitational force between the two masses will increase.

This is in compliance with universal law of gravitation proposed by newton.

Newton's law of universal gravitation states that "the gravitational force of attraction between two masses is directly proportional to the product of the masses and inversely proportional to the square of the distance them".

From law, we can establish that the gravitational force is directly proportional to the product of the masses between two bodies.

The higher the mass, the higher the gravitational force.

5. Which are forms of energy? Select all that apply.
slavikrds [6]

Answer:

There are mechanical energies. These consist of kinetic energy and gravitational potential energy.

Kinetic energy is the energy an object contains when it is in motion. Ex.: A car moving, a ball falling off of a building.

Gravitational potential energy is the potential for an object to do work at a certain height. If a 1 kg ball is placed 1 meter high, it has 9.8 Joules of potential energy, represented with the equation, Ug=mgh.

There are Non-Mechical Energies, which I assume you are trying to get. There is Thermal Energy, Electrical Energy, Light, Sound, Nuclear Energy, and Chemical Energy.

Thermal Energy is essentially heat. Friction causes thermal energy.

Electrical energy is potential difference. It is the work that can be done by a point charge.

Nuclear energy is like fission and fusion

Chemical energy is energy from chemical processses. Think, photosynthesis for example.

Sound is molecules hitting other molecules. It occurs a lot with friction as well.

Light is, well, you know what light is.

Balance the chemical equation got the reaction of benzene and hydrogen to form cyclohexane
lozanna [386]
C₆H₆  +  3H₂  →  C₆H₁₂

Benzene + 3 molecules of hydrogen = cyclohexane

So essentially what happens is that benzene contains three double bonds and when reacted with hydrogen then these three double bonds can be broken and the hydrogen bond to the tetravalent carbon to restore its for bonds forming cyclohexane
