What is the term for the degree of hotness or coldness of a body or environment?

• A. Temperature
• B. Humidity
• C. Pressure
• D. Volume

Answer: (A)

Temperature is the measure of how hot or cold something is. It reflects the average kinetic energy of the particles in a substance—when particles move faster, temperature rises; when they move slower, it falls. You read temperature with a thermometer, and it helps you distinguish a hot day from a cold day or a hot cup of coffee from a cold drink. Other terms describe different properties: humidity is the amount of moisture in the air, pressure is the force per unit area, and volume is how much space something occupies. So the degree of hotness or coldness is what temperature measures.
