If 11.9 kJ are used to heat a sample of water the temperature increases from 20.0°C to
Kipish [7]

Answer:

m=4.51g

Explanation:

Hello!

In this case, since the energy involved during a heating process is shown below:

Q=mCp\Delta T

Whereas the specific heat of water is 4.184 J/(g°C), we can compute the heated mass of water by the addition of 11.9 kJ (11900 J) of heat as shown below:

m=\frac{Q}{Cp\Delta T}

Thus, by plugging in, we obtain:

m=\frac{11900J}{4.184\frac{J}{g\°C}(650\°C-20.0\°C)}\\\\m=4.51g

Best regards!

The amount of energy needed to split the nucleus into individual protons and neutrons​
Mila [183]

Answer:

The correct answer is nuclear binding energy.

Explanation:

The least amount of energy, which is needed to distinguish an electron from an atom or to break the neutrons and protons from the nucleus of the atom is termed as the binding energy. This form of energy is also called separation energy. When a bound system is produced, the binding energy is equivalent to the mass defect less the concentration of the mass or energy discharged.  

There are many types of the binding energy of which the energy, which is needed to dissociate a nucleus into the individual neutrons and protons is known as the nuclear binding energy.
