A gas has a volume of 200. mL at 350. mm Hg. What will its volume be if the pressure is changed to 555. mm Hg

The final volume when pressure is changed is 126.1mL

Explanation:

Based on Boyle's law, in a gas the volume is inversely proportional to its pressure when temperature remains constant. The equation is:

P₁V₁ = P₂V₂

Where P is pressure and V volume of 1, intial state and 2, final state.

Computing the values of the problem:

350mmHg*200mL = 555mmHgV₂

126.1mmHg = V₂

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
