PLEASE HELP I WILL GIVE A TO THE CORRECT ANSWER Lab: Energy Transfer
What is the purpose of the lab?
What procedure did you use to complete the lab?
What charts, tables, or drawings would clearly show what you have learned in this lab?
If you could repeat the lab and make it better, what would you do differently and why?
The lab was where I had 2 glass blocks and I put aluminum on top of both and then I put
some pieces of chocolate on it. When I did that I lit a candle and put it under the chocolate. They all started melting the ones farther away from the candle melted slower. So I just need you to answer the questions please.

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
