Answer:
Alkenes of the type R–CH=CH–R can exist as cis and trans isomers;
 
        
             
        
        
        
<em>Thermal energy</em> is the sum of the kinetic and potential energies of all the particles in an object.
Assume that you have 250 gL of water and 1 kg of water at the same temperature.
Then, each water molecule has the same kinetic energy.
The larger sample contains four times as many molecules, so it contains four times as much thermal energy.
Thus, thermal energy is directly proportional to mass.
In symbols, <em>KE </em>∝ <em>m</em> or <em>KE = km</em>.
The graph of a direct proportion is a <em>straight line passing trough the origin</em>.
It should look something like the graph below.

Answer:
The answer to your question is 308.1 kPa
Explanation:
Data
Volume 1 = V1 = 4.75 l
Pressure 1 = P1 = 120 kPa
Volume 2 = V2 = 1.85 l
Pressure 2 = ?
Process
To solve this problem use Boyle's law.
                  P1V1 = P2V2
- Solve for P2
                  P2 = P1V1 / V2
- Substitution
                  P2 = (120 x 4.75) / 1.85
-Simplification
                  P2 = 570 / 1.85
-Result 
                   P2 = 308.1 kPa
