The speed will typically increase. It is hard to make a blanket statement though, because so much depends upon the type of medium being acted upon.
because the density of the medium changes with temprature
There are some factors. Temperature, medium are that factors.
No it is not true. When the temperature of the medium increases the speed of sound in that medium increases.
the speed of sound is equal to one machs.the speed,2 machs means that the object is travelling twice the speed of sound
Speed of sound depends on the density of the medium. As temperature increases density decreases due to expansion in the volume. Hence speed of sound gets affected by the change in temperature. Speed of sound is directly proportional to the square root of the temperature of the medium.

When you change density and temperature you effect the way sound travels through a medium.
Speed of sound depends on the density of the medium. As temperature increases density decreases due to expansion in the volume. Hence speed of sound gets affected by the change in temperature. Speed of sound is directly proportional to the square root of the temperature of the medium.

No it is not true. When the temperature of the medium increases the speed of sound in that medium increases.
The speed of sound depends upon elasticity and inertia of the medium which in turn depend upon the temperature of the medium.That's why speed of sound depends upon the temperature of the medium.
Yes, sound can change its medium.
Speed of sound increases with the increase in temperature of the medium .In fact the speed of sound is directly proportional to the square root of absolute temp. of the medium.

Formula for speed of sound c = 331 + 0.6 × ϑ ϑ = temperature in degrees celsius. At ϑ = 20°C we get a speed of sound c = 331 + 0.6 × 20 = 343 m/s. 1 °C change of temperature is equal to 60 cm/s change of speed of sound. The speed of sound changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure). The words "sound pressure at sea level" are incorrect and misleading in the case of "speed of sound". The temperature indication, however, is absolutely necessary. The changing of atmospheric pressure does not change the sound of musical instruments in a concert hall or in a room. Look at link: "Temperature Dependence of Physical Entities".
The speed of sound through the medium also increases.
