      [ Choose ]            scalar            vector      

density

      [ Choose ]            scalar            vector      

displacment

      [ Choose ]            scalar            vector      

Answer 1

1.Temperature is Scalar quantity,because for any material it has definite value(Magnitude) but it does not have a direction.

2.Velocity is a Vector quantity,because it has both direction and Magnitude.

3.Acceleration is a Vector quantity.again it has both direction and magnitude.

4.Mass is matter contained in body.it has a definite value but it does not have direction.So it is scalar quantity.

5.Density is defined as Mass per unit volume.Now both Mass and volume are Scalar quantity.So density is Scalar quantity.

6.Displacement has both magnitude and direction,so it is vector quantity.
