Question

- A copper calorimeter of mass 100 g and
temperature 30 °C contains water of mass
200 g and temperature 30 °C. If a piece of ice
of mass 40 g and temperature 0°C is added
to it, what will be the maximum temperature
of the mixture? [c (copper) = 0.1 cal/g. °C,
c (water) = 1 cal/g °C, L = 80 cal/g]​

Answer 1

=> Velocity of sound in gas at 27°C = 330 m/s.

To Find:

=> Velocity at 327°C.

Let velocity at 327°C be x,

So,

\sf{\implies \dfrac{27}{330}=\dfrac{327}{x}}⟹33027=x327

\sf{\implies \dfrac{330 \times 327}{27} = x}⟹27330×327=x

\sf{\implies x = 3996.6\;m/s}⟹x=3996.6m/s

{\boxed{\boxed{\bf{So,\;velocity\;at\;327^{\circ}C=3996.6\;m/s}}}}So,velocityat327∘C=3996.6m/s

my dear friend u can keep this as reference for this ok sorry yaar I couldn't get you the perfect answer for this question
