When the level of mercury inside a gas tube is higher than the level in the
reservoir, you find the correct pressure inside the tube by taking the outside
pressure reading and? _ the difference in the height of mercury.
(A) subtracting
(B) adding
(C) dividing by 13.6
(D) doing both (c) and (a)
If water is the liquid in question 12 instead of mercury, you can change the
height difference to an equivalent mercury expression by
(A) dividing by 13.6
(B) multiplying by 13.6
(C) adding 13.6
(D) subtracting 13.6
Standard conditions are

(B) 273 K and 760 mm Hg
(C) 273°C and 760 mm Hg
(D) 4°C and 7.6 mm Hg- When a gas is collected over water, the pressure is corrected by
(A) adding the vapor pressure of water
(B) multiplying by the vapor pressure of water
(C) subtracting the vapor pressure of water at that temperature
