Answer:
Carbon - 13 
Explanation:
For most of the elements other than that of hydrogen, the isotopes are named for the mass number. 
Example : Carbon atoms with 6 neutrons have mass number of 12 ( as  ), so they are known as carbon-12.
 ), so they are known as carbon-12. 
Given that:
Protons = 6
Neutrons = 7
Mass = 6 + 7 = 13 
So the name is Carbon - 13 . The symbol is 
 
        
                    
             
        
        
        
Answer:
energy known as the latent heat of vaporization is required to break the hydrogen bonds. At 100 °C, 540 calories per gram of water are needed to convert one gram of liquid water to one gram of water vapour under normal pressure.

The answer is A! Heat energy is thermal energy. To remember all Energy use M.E.L.T.S!
M- Mechanical energy
E- Electrical energy
L- Light energy 
T- Thermal energy
S- Sound energy
