Introductory Chemistry Questions

In this problem, we are asked to define chemistry and explain four ways it contributes to daily life based on a specific scenario involving farming, medicine, fuel, and manufacturing.

Let's start with part A: defining chemistry. Chemistry is the scientific study of the properties and behavior of matter. It looks at the substances that make up matter, how they interact, and how they change to form new substances.

Now, let's move to part B. We need to identify four contributions of chemistry based on the scenario provided. The scenario mentions a farmer using fertilizers, a pharmacist preparing medicines, a petrol station supplying fuel, and a manufacturer producing plastics.

First, in agriculture, chemistry is used to develop fertilizers that provide essential nutrients to the soil, ensuring better crop yields and food security.
