This is theoretically the lowest possible temperature where nothing could be colder and no heat energy remains in a substance. It's like turning down your thermostat until there's absolutely no warmth left!
Kelvin Scale: This scale measures thermodynamic temperature where absolute zero is zero Kelvin. It’s like Fahrenheit or Celsius but starts at absolute zero – so no negative numbers!
Another gas law which states that at constant temperature, pressure and volume are inversely related. Like squeezing a stress ball - as you squeeze harder (increase pressure), its size (volume) decreases.
