Calculating the Volume of the Tank:

To calculate the volume of the tank, we need to multiply its length, width, and depth. However, we need to ensure that all the measurements are in the same unit.

Given:
Length = 1.6 m
Width = 5 cm = 0.05 m
Depth = 50 mm = 0.05 m

Converting the Measurements:

Since the width and depth are given in different units (cm and mm), we need to convert them to meters before proceeding with the calculation.

1 cm = 0.01 m
1 mm = 0.001 m

Width = 5 cm x 0.01 m/cm = 0.05 m
Depth = 50 mm x 0.001 m/mm = 0.05 m

Now that all the measurements are in meters, we can calculate the volume of the tank.

Calculating Volume:

Volume = Length x Width x Depth
Volume = 1.6 m x 0.05 m x 0.05 m
Volume = 0.004 m³

Converting to Litres:

Since the volume is currently in cubic meters, we need to convert it to litres.

1 m³ = 1000 L

Volume (in litres) = Volume (in cubic meters) x 1000
Volume (in litres) = 0.004 m³ x 1000
Volume (in litres) = 4 L

Therefore, the volume of the tank is 4 litres.

Importance and Scope of Chemistry:

Chemistry is a branch of science that deals with the study of matter and its properties, composition, and interactions. It plays a crucial role in various aspects of our daily lives and has a wide scope of applications. Some of the key reasons why chemistry is important are:

1. Understanding the world: Chemistry helps us understand the composition, structure, and behavior of matter. It explains why substances behave the way they do and allows us to make predictions about their properties.

2. Development of new materials: Chemistry is essential for the development of new materials with improved properties and functionalities. It enables the creation of innovative products, such as advanced polymers, pharmaceuticals, and nanomaterials.

3. Environmental protection: Chemistry plays a vital role in addressing environmental issues. It helps in the development of sustainable technologies, pollution control measures, and the study of climate change. It also provides insights into the impact of chemicals on ecosystems and human health.

4. Medicine and healthcare: Chemistry is central to the development of pharmaceutical drugs, diagnostics, and medical treatments. It helps in understanding the mechanisms of diseases, designing effective drugs, and developing new therapeutic approaches.

5. Energy production and storage: Chemistry is crucial for the development of renewable energy sources, such as solar cells, fuel cells, and batteries. It enables the study of energy conversion processes, energy storage materials, and the optimization of energy efficiency.

6. Food and agriculture: Chemistry contributes to improving food production, preservation, and safety. It involves the study of food composition, nutritional value, additives, and the development of sustainable agricultural practices.

7. Forensic science: Chemistry plays a crucial role in forensic investigations, including the analysis of crime scene evidence, identification of drugs and toxins, and the study of trace elements and DNA analysis.
