Questions with complete solution 2025
What is the difference between extensive and intensive properties? - correct
answer ✔An 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 answer ✔9/5C+32
Difference between molecular and ionic compounds - correct answer
✔Molecular= non-metals only
Ionic= metals and non-metals
Fahrenheit to Celsius - correct answer ✔5/9(F-32)
Celsius to Kelvin - correct answer ✔C+ 273.15
Atomic Theory - correct answer ✔1. 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
