Question

what is the unit unit of density explain the effect of temperature on it​

Answer 1

Answer:

The unit of density is kilogram per cubic metre (kg/m3).

Answer 2

Answer:

velocity of sound in a gas is directly proportional to the square root of its temperature. velocity of sound in gas increase with increase in temperature. velocity at temperature T is given by the following equation. Vt =( Vo + 0.61T) ms -1

here, Vo is the velocity of sound in the gas at 0°C.for air,Vo = 331 ms -1 .hence, the velocity of sound changes by 0.61 ms -1 when temperature changes by each degree Celsius. it's unit is ( kg/m3) .
