A mixture of diatomic gases is obtained by mixing m_1 and m_2 masses of two gases, with velocity of sound in them c_1 and c_2respectively. Determine the velocity of sound in the mixture of gases. (Temperature of the gas remains constant)

Answer»

`C= SQRT( (m_1c_2^2 - m_2c_1^2)/(m_2 + m_1))`
`c = sqrt((m_1c_2^2 + m_2c_1^2)/(m_1 + m_2))`
`c = sqrt((m_1c_1^2 + m_2c_2^2)/(m_1 + m_2))`
`c = sqrt((m_1 c_2^2 + m_2c_1^2)/(m_1 - m_2))`
