WITH CORRECT QUESTIONS AND
ANSWERS 2025
What is the difference between extensive and intensive properties? - CORRECT-ANSWERSAn
extensive property depends on the amount of matter; an intensive property depends on the
type of matter. Mass and volume are extensive properties. Color and hardness are intensive
properties.
Celsius to Fahrenheit - CORRECT-ANSWERS9/5C+32
Difference between molecular and ionic compounds - CORRECT-ANSWERSMolecular= non-
metals only
Ionic= metals and non-metals
, Fahrenheit to Celsius - CORRECT-ANSWERS5/9(F-32)
Celsius to Kelvin - CORRECT-ANSWERSC+ 273.15
Atomic Theory - CORRECT-ANSWERS1. Element composed of microscopic, indivisible spheres
2. Atoms of the same type= identical
3. Atoms combine in simple whole number ratios
4. The numbers and kinds of elements in a compound are constant
5. Atoms are neither created nor destroyed (conservation of mass)
Why is temperature
