Question

You are playing with a helium balloon on a warm Colorado day. Suddenly, the Celsius temperature doubles. Which of the following is true?

a. The volume of the balloon will double. b. The pressure inside the balloon will double. c. The actual temperatures are needed to answer this question. d. The volume of the balloon will slightly increase. e. The volume of the balloon will decrease.

Answer 1

consider the equation PV = nRT P = pressure of the gas - Volume T - Temperature n = no. of moles R = universal gas constant. a) At constant pressure the volume es directly proportional to Temperature. VT T2 = 27, (Given) 12V = V2 | i The volume of the balloon well double. (True) At constant volume 6) PT 1 T2 = 21, 2T W

. The pressure inside the balloon will double (True). c) Actually when we compare two equations and the temperatures in the equations are written in terms of Other (T2=2T). Then the temperature team will be cam called. Not True. No requrire ment of Tempegature.

d) As per the option a proof the twice the Volume. Volume becomes So, It is not slight mcgease. At ts. more than slight mogease in volume False. (slightly meaning - to a small degree not considerably the volume will increase e) False
