No doubt you already have a good idea of what temperature is. You might say that it’s how warm or cool something feels. In physics, temperature is defined as the average kinetic energy of the particles of matter. When particles of matter move more quickly, they have more kinetic energy, so their temperature is higher. With a higher temperature, matter feels warmer. When particles move more slowly, they have less kinetic energy on average, so their temperature is lower. With a lower temperature, matter feels cooler.
Jane enjoyed sitting on her porch in the morning enjoying the cool air. However by afternoon she was uncomfortable outside. The temperature had reason 15 degrees so she went inside were it was air conditioned and much cooler.
was the kinetic energy of the air increasing or decreasing as the day went on?
