Document Summary
Pressure, temperature (thermal energy), volume, moles (n), work, heat. A balloon on top of a bed of nails will not pop if force is exerted on it but will pop if it is only on one nail and force is exerted on it. This is an example of how pressure works. Large area = low pressure, a smaller area = high pressure. Pressure (p) = force (n) divided by area (m squared) 1 pascal = 1 newton (n) divided by 1 meter (m) squared. This is the space (3 dimensional) that an object occupied. Conceptually we all understand temperate, like we are physically capable of telling whether or not we need to wear a coat outside. A measurement with a thermometer is more accurate. 0 on a kelvin scale is the point when all motion stops. Fahrenheit and celsius are in degrees, kelvins are just kelvins.
