A man heats a balloon in the oven. If the balloon initially has a volume of 1.38 L and a temperature of 20 °C, what will the volume of the balloon be after he heats it to a temperature
of 300 °C?

the product of the pressure and volume is also constant

im doing test rn im going with 2 but ill give answer if itss wrong,   : )

5 structural isomers

the isomers are:

n-exane :   ch3ch2ch2ch2ch2ch3

2-methylpentane :   ch3ch(ch3)ch2ch2ch3

3-methylpentane :   ch3ch2ch(ch3)ch2ch3

2,3-dimethylbutane :   (ch3)2chch(ch3)2

2,2-dimethylbutane :   (ch3)3cch2ch3
