Name the equipment used in measuring thermal behaviour of water

Options

A. SEM
B. Differential scanning calorimeter
C. Real time PCR
D. MALDI - TOF

Answer

To answer the question "Name the equipment used in measuring thermal behaviour of water," we will analyze the given options step by step.

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- A) SEM (Scanning Electron Microscope)
- B) Differential Scanning Calorimeter
- C) Real-Time PCR
- D) MALDI-TOF (Matrix-Assisted Laser Desorption/Ionization Time-of-Flight)

2. **Evaluate Option A - SEM**:
- The SEM is used for imaging surfaces at a microscopic level. It does not measure thermal properties.
- **Conclusion**: Incorrect option.

3. **Evaluate Option B - Differential Scanning Calorimeter**:
- The Differential Scanning Calorimeter (DSC) is specifically designed to measure the heat flow associated with phase transitions in materials, including water. It measures the difference in heat required to increase the temperature of a sample compared to a reference.
- **Conclusion**: Correct option.

4. **Evaluate Option C - Real-Time PCR**:
- Real-Time PCR is a technique used for amplifying DNA and does not relate to thermal behavior measurements.
- **Conclusion**: Incorrect option.

5. **Evaluate Option D - MALDI-TOF**:
- MALDI-TOF is a mass spectrometry technique used for identifying biomolecules and does not measure thermal properties.
- **Conclusion**: Incorrect option.

### Final Answer:
The equipment used in measuring the thermal behaviour of water is the **Differential Scanning Calorimeter**.
