Q-Value Solution

STEP 0: Pre-Calculation Summary

Formula Used

Q Value = Initial Energy-Final Energy
Q = U_i-U_f
This formula uses 3 Variables

Variables Used

Q Value - (Measured in Joule) - Q Value is the amount of energy absorbed or released during the nuclear reaction.
Initial Energy - (Measured in Joule) - Initial Energy is the amount of energy before nuclear reaction.
Final Energy - (Measured in Joule) - Final Energy is the amount of energy after nuclear reaction.

STEP 1: Convert Input(s) to Base Unit

Initial Energy: 20 Joule --> 20 Joule No Conversion Required
Final Energy: 10 Joule --> 10 Joule No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = U_i-U_f --> 20-10

Evaluating ... ...

Q = 10

STEP 3: Convert Result to Output's Unit

10 Joule --> No Conversion Required

FINAL ANSWER

10 Joule <-- Q Value

(Calculation completed in 00.020 seconds)

Binding Energy

Go Binding Energy = (Atomic Number*Mass of Proton+(Mass Number-Atomic Number)*Mass of Neutron-Mass of Atom)*[c]^2

Mass Defect

Go Mass Defect = Atomic Number*Mass of Proton+(Mass Number-Atomic Number)*Mass of Neutron-Mass of Atom

Population at Time t

Go Number of Particles at Time t = Number of Particles in Sample Initially*e^(-(Decay Constant*Time)/(3.156*10^7))

Population after N Half Lives

Go Number of Particles at Time t = Number of Particles in Sample Initially/(2^(Number of Half Lives))

Decay Rate

Go Decay Rate = -Decay Constant*Total Number of Particles in Sample

Nuclear Radius

Go Nuclear Radius = Radius of Nucleon*Mass Number^(1/3)

Change in Mass in Nuclear Reaction

Go Mass Defect = Mass Reactant-Mass Product

Q-Value

Go Q Value = Initial Energy-Final Energy

Half Life for Nuclear Decay

Go Half Life Period = 0.693/Decay Constant

Average Life

Go Average Life = 1/Decay Constant

Energy Released in Nuclear Reaction

Go Energy = Mass Defect*[c]^2

Q-Value Formula

Q Value = Initial Energy-Final Energy
Q = U_i-U_f

What can change in a nuclear reaction?

Unlike a chemical reaction, a nuclear reaction results in a significant change in mass and an associated change of energy, as described by Einstein's equation. In nuclear fission, nuclei split into lighter nuclei with an accompanying release of multiple neutrons and large amounts of energy.

How to Calculate Q-Value?

Q-Value calculator uses Q Value = Initial Energy-Final Energy to calculate the Q Value, The Q-Value formula is defined as the amount of energy absorbed or released during the nuclear reaction. Q Value is denoted by Q symbol.

How to calculate Q-Value using this online calculator? To use this online calculator for Q-Value, enter Initial Energy (U_i) & Final Energy (U_f) and hit the calculate button. Here is how the Q-Value calculation can be explained with given input values -> 10 = 20-10.

FAQ

What is Q-Value?

The Q-Value formula is defined as the amount of energy absorbed or released during the nuclear reaction and is represented as Q = U_i-U_f or Q Value = Initial Energy-Final Energy. Initial Energy is the amount of energy before nuclear reaction & Final Energy is the amount of energy after nuclear reaction.

How to calculate Q-Value?

The Q-Value formula is defined as the amount of energy absorbed or released during the nuclear reaction is calculated using Q Value = Initial Energy-Final Energy. To calculate Q-Value, you need Initial Energy (U_i) & Final Energy (U_f). With our tool, you need to enter the respective value for Initial Energy & Final Energy and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
