The ratio of mass to volume is called density. The equation looks like Density= Mass/Volume. Some units for density These notes represent a detailed interpretation of the professor’s lecture.

Mass can be measured with a balance.EnergyEnergy has different forms: Kinetic, Potential, Electrical, Chemical, and Thermal. One form of energy CAN change to another (i.e. Potential to Kinetic). The units of energy are Joules (J) for heat. The other is, calories or the energy to raise 1 g of H2O by 1 degree Celsius. Changes in energy are classified as, Exergonic, Endergonic, Exothermic or Endothermic.TemperatureTemperature is a form of energy and it has 3 main types of measurements Fahrenheit, Celsius and Kelvin. They each have different measurements for freezing, body temperature and boiling of water and everything in
