Answer : The new speed will be, 1.098v

Explanation :

The formula used for speed of sound in a container of gas is:

c=\sqrt{\frac{\gamma RT}{M}}

where,

c = speed of sound

R = gas constant

\gamma = adiabatic constant

T = absolute temperature

M = molecular mass of gas

As, c\propto \sqrt{T}

or, we can say that

\frac{c_1}{c_2}=\sqrt{\frac{T_1}{T_2}}            .............(1)

Given:

T_1 = 20.0^oC=273+20.0=293K

T_1 = 80.0^oC=273+80.0=353K

c_1 = v

Now put all the given values in the above formula 1, we get:

\frac{v}{c_2}=\sqrt{\frac{293}{353}}

c_2=1.098v

Thus, the new speed will be, 1.098v

Propane (c3h8) is burned in oxygen to produce carbon dioxide and water. the heat of combustion of propane is -2012 kj/mole. how
Olegator [25]
C_{3} H_{8} + 5 O_{2} ---\ \textgreater \  3CO_{2}  +4H_{2}O    (-2012 \frac{kJ}{mol} )


3 mol                10 mol


C_{3}H_{8} is /excess /reactant

because 3 mol propane require 15 mol oxygen (by reaction)

5 mol oxygen ---1 mol propane, so

10 mol oxygen ---2 mol propane

Only 2 mole propane will be burned,

so 

2012 ( kJ/mol)*2 mol =4024 KJ heat will be given off

Correct answer is number 4.
