Hot, humid summer days can feel unbearable sometimes. Humidity, or the amount of moisture in the air, can make the temperature feel warmer, as our sweat is slower to evaporate. Not only is the muggy air uncomfortable, but it can cause our bodies to overheat, exhaust easily, and poses a potential danger to our health.
Quick Answer. Temperature affects air pressure by causing the air to either become more or less dense, which expands or lowers its pressure. Warm air is less dense than cold air, and as air becomes less dense, its pressure increases. Basically, the cooler the air, the more it contracts and becomes more dense.
