Question 1: What is temperature, and how does it differ from heat?
Temperature quantifies the average kinetic energy of the particles within a substance, indicating its hotness or coldness. Heat, on the other hand, measures the energy transferred between objects or systems due to temperature differences.
Question 2: Which temperature scale is most frequently used worldwide?
The Celsius scale is the most widely adopted temperature scale globally. It defines 0°C as the freezing point of water and 100°C as its boiling point.
Question 3: What factors can affect temperature readings?
Several factors can influence temperature readings, including the type of thermometer being used, the presence of external heat sources, and the thermal conductivity of the substance being measured.
Question 4: How does atmospheric pressure impact temperature?
Atmospheric pressure can affect temperature, as higher pressure generally leads to higher temperatures. This is because increased pressure compresses the air molecules, causing them to generate more heat through increased collisions.
Question 5: What is the relationship between temperature and thermal expansion?
Temperature and thermal expansion are directly related. As temperature rises, most substances expand because the increased kinetic energy causes their particles to move further apart.
Question 6: Can temperature be negative?
In the Celsius scale, negative temperatures are possible and indicate temperatures below the freezing point of water (0°C). However, in the Kelvin scale, the absolute zero point is defined as 0 K (-273.15°C), and negative temperatures are not possible.
By understanding these fundamental concepts, you can better comprehend temperature and its role in various scientific and everyday applications.
