What term describes how hot or cold an object is and is measured with a thermometer?

• A. Temperature
• B. Mixture
• C. Solution
• D. Energy

Answer: (A)

Temperature describes how hot or cold something is, and a thermometer is the tool used to measure it. It reflects the average kinetic energy of particles in a substance and is read on scales like Celsius, Fahrenheit, or Kelvin. Energy relates to how much heat could be transferred, but the thermometer’s reading specifically tells you the thermal state, not the total energy stored. Mixture and solution refer to substances formed by combining materials, not to how hot or cold they are.
