A sample of gas has an initial volume of 13 at a pressure of 1. Substitute, , and to calculate : Exercise 6 - Enhanced - with Feedback MISSED THIS? Read Section 6 (Page) Watch KCV 6. Solving this equation for gives Before substituting the numerical values to calculate, convert the initial and the final temperatures to kelvins. ANSWER: ANSWER: Correct Charles's law is where and are the initial volume and temperature of the gas and and are the final volume and temperature. Express your answers in kelvins to three significant figures separated by a comma. Convert the initial and final temperatures of the sample to kelvins. Convert between degrees Celsius and kelvins The temperature values used in the simple gas laws are in kelvins. Part A What is its volume at the final temperature? (Assume constant pressure.) Express your answer in millililters to three significant figures. A 49 sample of gas in a cylinder is warmed from 18 to 86.

ANSWER: Correct The pressure in is converted to the pressure in by dividing by 760. The first is to convert to, and the second is to convert to. ANSWER: Correct Converting from to requires two steps. ANSWER: Correct The units of and are equivalent. The pressure on top of Mount Everest (29,029 ) averages about 235. Grading Policy Exercise 6 - Enhanced - with Feedback MISSED THIS?
