Density is mass divided by volume. rho=m/v. So, v=m/rho. In frank's case this is 80/8 = 10 cm^3.
Molecular Geometry is the three-dimensional structure or arrangement of atoms in a molecule.
Kinetic energy.
Kinetic energy is the type of energy observed in moving objects. In this case the football player is running, ie moving, so he/she must have kinetic energy.
Compounds are elements that are chemically combined, like water for example (it’s both hydrogen and oxygen.)
Water and wind cause mechanical weathering and produce angular rocks, sheer canyon walls, and pebble-covered surfaces.
