I think D, because water evaporates. Once it gets hot. Then condensation. I think
Mass of the water : 2.23 g
<h3>Furter explanation</h3>
Heat
Q = m.c.Δt
m= mass, g
c = heat capacity, for water : 4.18 J/g° C.
ΔT = temperature
Q= 140 J
Δt = 75 - 60 = 15
mass of the water :
Feathers have more density and less have more mass, feather is super light and a POUND of led isnt
DNA
sorry if it’s wrong, but that answer seems reasonable
