The gas in the piston is at constant temperature. A student increases the pressure on the piston from 2 atm to 3 atm. The observ
ation will be summarized in a row of the incomplete table below. 1
Boyle's law

2
Charles’s law
?

3
Gay-Lussac’s law
?

Which row of the table and which observation would the student fill?
row 1, volume decreases when temperature decreases
row 1, volume decreases when pressure increases
row 3, volume decreases when temperature decreases
row 3, volume decreases when pressure increases
<span>The answer is row 1, volume decreases when pressure increases. The given condition is a demonstration of Boyle's Law, which tells that the volume of a given amount of gas reserved at constant temperature is contrariwise proportional to the pressure. When the pressure is augmented by pushing the piston downwards, the gas will be compacted and its volume will decrease.</span>
the reason is that in a solid state the molecules have little kinetic energy to move and so they have restricted movement and so it remains solid once heat is applied the molecules gain enough energy to move and so they turn into a liquid and move according to the laws of physics
The question is incomplete as some details are missing. Here is the complete question ; A chemist adds 45.0mL of a 0.434M copper(II) sulfate CuSO4 solution to a reaction flask. Calculate the mass in grams of copper(II) sulfate the chemist has added to the flask. Round your answer to 2 significant digits
