## What is the meaning of Q in science?

In nuclear physics and chemistry, the Q value for a reaction is the amount of energy absorbed or released during the nuclear reaction. The value relates to the enthalpy of a chemical reaction or the energy of radioactive decay products.

What does Q stand for in physics?

Big Q represents the source charge which creates the electric field. Little q represents the test charge which is used to measure the strength of the electric field at a given location surrounding the source charge. Give considerable attention to the charge quantity – Q or q – being used in each equation.

### What is Q in nuclear fusion?

A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state.

### What is Q in electric field?

The symbol q in the equation is the quantity of charge on the test charge (not the source charge). Recall that the electric field strength is defined in terms of how it is measured or tested; thus, the test charge finds its way into the equation. Electric field is the force per quantity of charge on the test charge.

What does Q stand for in math?

The term rational in reference to the set Q refers to the fact that a rational number represents a ratio of two integers. In mathematics, “rational” is often used as a noun abbreviating “rational number”.

#### What is disintegration energy Q?

The disintegration energy, sometimes also known as the Q-value, is the energy that is absorbed or released when a nuclear reaction takes place. The Q-value is positive if the reaction is exothermic and negative if the reaction is endothermic.
