Which law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pressure conditions? boyle’s law charles’s law dalton’s law gay-lussac’s law

Charles's Law i think

Answer is: Charles’s law.

Charle's law (the temperature-volume law): the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature:  V₁/T₁ = V₂/T₂.  

For example:

V₁(gas) = 20.0 L; initial volume.

T₁(gas) = 280 K.; initial temperature

V₂(gas) = 10.0 L; final volume

T₂(gas) = ?; final temperature.

20.0 L/ 280 K = 10.0 L / T₂.  

T₂ = 140 K.  

As the volume goes down, the temperature also goes down, and vice-versa.  

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)

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
