• AVolume
• BHumidity
• CPressure
• DTemperature

• A
  12% (2)
• B
  6% (1)
• C
  6% (1)
• D
  76% (13)

Explanation

Temperature is the correct answer because it is defined as the measure of the degree of hotness or coldness of a substance - in other words, it quantifies heat intensity on a scale (Celsius, Fahrenheit, or Kelvin). Volume refers to the amount of space an object occupies and has nothing to do with heat intensity. Humidity measures the amount of water vapor in the air, which can affect how heat feels but is not itself a measure of heat intensity. Pressure describes the force applied per unit area and, while it can be related to temperature in certain physical processes, it is not a direct measure of heat intensity.

Memory tip: Think of a thermometer - the tool you use to measure temperature - as your "heat intensity meter." The word "temperature" shares its root with "temper," meaning degree or level, which reinforces that it measures the level of heat.
