Answer:
When the charcoal burned, it turned into a gas which caused the mass to change.
Explanation:
The volume of the steel that is described above is obtained by water displacement method. This means that the volume can be calculated by subtracting the initial volume from the final volume. This will give us an answer of,
volume of steel = 55.5 mL - 45 mL = 10.5 mL
Answer:
Surface tension
Explanation:
A water strider (water bug) is able to walk on water because of water’s Surface tension.
Surface tension is phenomenon in which in liquid where it shrinks itself to its minimum surface area possible, it is very much visible in water surface because of high attraction between the water molecule.
Flat as more oxygen and water can react over it think of it like this would a cube rust faster than a sheet
B, water and ice are the main causes .
