Heat that flows by conduction is the transfer of thermal energy between substances in contact. What must occur for this to happen? TA B Block A has a higher temperature than block B heat flow The two blocks are the same temperature and heat flow stops Heatis transferred from the wamer block to the cooler block 2012 Encyclopædia Batannlea, Inc. B B heat flow

Heat is transferred from the warmer block to the cooler block

Explanation:

Heat transfer by conduction involves two or more solids. The heat generally moves from a part at higher temperature to one with a lower temperature.

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
