An ideal gas cannot be liquified because forces between the molecules are negligible.

The odometer or the odograph is an instrument used to indicate the distance travelled by the vehicle.

If an object moves with some velocity that means the magnitude and direction of the object changes i.e, the object moves with some acceleration. Hence, if the object moves with constant velocity, no change in direction and magnitude of speed i.e, no acceleration = 0 acceleration.

Glass is made from heating of sand. To melt sand to make glass, the temperature needed is above 1800 deg celcius.
