Which element shows heat and cold?

Correct answer: Temperature

The direct answer is C, Temperature. Temperature tells us how hot or cold the atmosphere is. It is measured with a thermometer and is one of the basic elements used to describe weather and climate. To solve the question, match the phrase “heat and cold” with the measurement that directly expresses them. Option A, humidity, means the amount of water vapour in the air. It may make air feel hotter or cooler, but it does not directly measure heat and cold. Option B, air pressure, is the force exerted by air and is related to weather systems, but it does not directly state how hot or cold the air is. Option C is correct because temperature directly gives the degree of warmth or coldness. Option D, wind direction, tells where the wind comes from or moves toward; it does not measure heat. Memory cue: hot or cold means temperature; wetness means humidity; force of air means pressure.
