8:56 AM oo T-Mobile charleslawduong7.blogspot.com l A 50.0 ml soap bubble is blown in a 27.0 C room. It drifts out an open window and lands in a snow bank at -3.0°C. What is its new volume? 2) A balloon was inflated to a volume of 5.0 liters at a temperature of 7.0°C. It landed in an oven and was heated to 147 C. What is its new volume? 3) During the day at 27 C a cylinder with a sliding top contains 20.0 liters of air. At night it only holds 19 What is the temperature at night? Give the answer in Kelvin and OC? 4) A container holds 50.0 mL of nitrogen at 25 C and a pressure of 736 mm Hg. What will be its volume if the temperature increases by 3 C 5 A sample of oxygen occupies a volume of 160 dm at 91o C. What will be volume of oxygen when the temperature drops to 0.00° C? 6) A sample of hydrogen has an initial temperature of 50. C. When the temperature is lowered to -5.0 C the volume of hydrogen becomes 212 cm What was the initial volume of the hydrogen in dm 7) 568 cm of chlorine at 25° C will occupy what volume at -25° C while the pressure remains constant?

Explanation / Answer

here ,

1_ volume of soap = 50 ml

initial temperature , Ti = 27 degree C

Ti = 27 + 273 = 300 K

Tf = -3 degree C = 273 - 3 = 270 K

Tf = 270 K

for the final volume

Vi/Ti = Vf/Tf

50/300 = Vf/270

Vf = 45 ml

the final volume is 45 ml
