High temperature means that the particles of an object are moving faster.
True
Mercury or alcohol in thermometers contract when heated.
False

True
Study Notes
What is Temperature?
- Temperature is a measure of how hot or cold an object is.
- The most common units for measuring temperature are degrees Celsius (°C), Fahrenheit (°F), and Kelvin (K).
- Temperature is related to the energy of an object's particles: higher temperature means more energy and faster movement, while lower temperature means less energy and slower movement.
Measuring Heat and Temperature
- Thermometers are the most common tool for measuring temperature, available in digital or analogue forms.
- Thermometers work by using a liquid (such as mercury or alcohol) that expands when heated and contracts when cooled.
- Heat can be measured using a calorimeter, which monitors the heat released or absorbed during a chemical reaction.
Converting Temperature
- Temperature conversions can be made between Celsius and Fahrenheit scales.
- Examples of conversions include 10°C equivalent to 50°F, and 37°C equivalent to 98.6°F.
Learn about temperature, its measurement units, and how it relates to the energy of an object's particles. Understand the concept of thermometers and their role in measuring heat and temperature.
