It has more density when it sinks because the water pushes away thats why people float they are less dense
Q = m c T
c= 0.140 j/(g x °c)
m= 250.0g
T =52
hope you can solve it now
I'm not sure what it asks, but it answers
- how many protons are in the nucleus
- how many electrons are in the atom
- where it sits in the periodic table
- If the periodic table is divided in the modern way, it gives a good indicator of whether you are speaking about a metal, a non metal or neither.
