1) Heat is: a) The transfer of kinetic energy from an object to another. b) How hot or cold an object is. c) The transfer of thermal energy from warmer to cooler body.  2) A substance made of two or more different kind of atoms is called: a) Element b) Compound c) molecule 3) Gas particles move faster than liquid particles because: a) They have higher kinetic energy than liquid particles. b) They are heavier than liquid particles. c) Because they are smaller in size. 4) If you left a cup of water for 2 days, you will eventually find it empty, that is due to: a) Melting. b) chemical change c) vaporization 5) The smallest building unit of matter is called : a) Cell b) Atom c) element 6) If you left an inflated balloon outside in a sunny day, you will eventually find it bigger in size or it might even explode, this happens due to : a) Condensation b) Thermal contraction c) Thermal expansion 7) In the previous question, if you take the balloon back inside where the AC is on, it will get smaller after a while.
