Write a hypothesis for Partl of the lab, which is about the
effect of mass on the ability of an object to absorb or
release thermal energy. Use the format of "if... then...
because ..."and be sure to answer this part of the lesson
question: "How does mass affect thermal energy
transfer?"

for points guys

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
