Kelvin vs
NOT ZERO
Kelvin = shows energy Internal Energy at minimum
→ Cannot have negative energy > No motion of molecules
↳ Therefore lowest energy ☐ absolute Zero
Zero Ek of Molecules
Celsius = shows temperature
Temperature in °C + 273.5 = Temperature in Kelvin
Standard Temperature + Pressure
Some questions will ask to complete a calculation
" assuming standard temperature and pressure"
