DONE

Volume is the  dependent  variable, and the

temperature of the gas is the  independent  variable.

Explanation:

Variables Independent Variable: temperature; Dependent Variable: volume

Constants: pressure and number of molecules

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
