100
Volume ~ Units (Solid)
How much space an object takes up cm3
100
How does heat affect the density of water
Hotter the molecules spread out-less dense Colder the molecules slow down - more dense- not water
100
Density of water
1g/mL
100
v+m same
same density
100
Equation for density
D=M/V
200
Mass ~ Units
The amount of matter in an object Grams (g)
200
will 0.3 sink or float in room temp
float
200
cold water molecules
tightly packed together
200
same v diff m less dense y
smaller mass bc less molecules
200
is the density of a pool of water and a cup the same
yea
300
Density ~ UNITS SOLID
A measure for how tightly packed molecules are for a given volume. Tells us how much matter there is in a object of a given volume g/cm3
300
will 9 sink or float in room temp
sink
300
room temp molecules
equally spread apart
300
500mL 1000mL would density b doubled y
no ratio stays same divide m by v they will b the same
300
density of mass= 78 v=194

how does heat affect the movement of atoms
hot= atoms move faster spread out cold atoms slow down get close

draw 2 object diff m + v
draw it
