Of the following terms are used for denoting concentration of a solution, the one which does not get affected by temperature is:

Options

A. Morality
B. Molality
C. Normality
D. Formality

Answer

To determine which term used for denoting the concentration of a solution is not affected by temperature, we need to analyze the different concentration terms. Here are the common terms used for concentration:

1. **Molarity (M)**: This is defined as the number of moles of solute per liter of solution (mol/L). Molarity is affected by temperature because the volume of the solution can change with temperature.

2. **Molality (m)**: This is defined as the number of moles of solute per kilogram of solvent (mol/kg). Molality is not affected by temperature because the mass of the solvent does not change with temperature.

3. **Mass percent**: This is defined as the mass of solute divided by the total mass of the solution, multiplied by 100. Mass percent is also not affected by temperature as it is based on mass, which remains constant regardless of temperature.

4. **Volume percent**: This is defined as the volume of solute divided by the total volume of the solution, multiplied by 100. Volume percent is affected by temperature because the volume of the solution can change with temperature.

Now, based on this analysis, we can conclude that:

- **Molarity** is affected by temperature.
- **Molality** is not affected by temperature.
- **Mass percent** is not affected by temperature.
- **Volume percent** is affected by temperature.

Among these, the terms that are not affected by temperature are **molality** and **mass percent**. However, since the question asks for one term, the most commonly accepted answer is **molality**.

### Final Answer:
The term that does not get affected by temperature is **molality**.
