If a bird at a constant speed going north and then turns west keeping the same speed does the momentum change

yes

Explanation:

momentum depends on velocity so when velocity changes (which is when speed or direction changes) momentum changes

for example angular momentum is the momentum due to rotational motion which includes changes in direction

vapour or gas assuming atmospheriv pressure

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
