Correct Answer:
Temperature is a measure of how hot or cold something is.
Explanation:
Temperature is a physical quantity that indicates the level of heat present in an object, substance, or environment. It reflects the average kinetic energy of the particles within a material. In simpler terms, it shows how fast or slow the particles inside an object are moving. When particles move faster, the temperature is higher, and the object feels hotter. When the particles move more slowly, the temperature is lower, and the object feels colder.
Scientists measure temperature using thermometers, which can be based on different principles. Common types include liquid thermometers that use mercury or alcohol, digital thermometers, and infrared thermometers. The most widely used units of temperature are degrees Celsius (°C), degrees Fahrenheit (°F), and Kelvin (K).
Temperature plays a crucial role in daily life and scientific studies. For example, knowing the temperature helps us decide what clothes to wear, how to store food, and how to maintain safe conditions in homes, workplaces, or vehicles. In industries, temperature control is important for manufacturing, preserving products, and conducting experiments.
In science, temperature is also related to states of matter. When heat is added to a substance, its temperature rises, and it may change from a solid to a liquid or from a liquid to a gas. Likewise, removing heat lowers the temperature, which can cause gases to become liquids or liquids to become solids.
Temperature is not the same as heat, although they are related. Heat refers to the energy transferred from one object to another due to a temperature difference, while temperature itself is a measure of how hot or cold something is at a specific moment.
