Which one of the following is a vector quantity?

  • Temperature gradient checkmark
  • Mass
  • Work
  • Time

The correct answer is: A

Explanation

Temperature gradient(Tg) = DT ÷ L = T2 – T1 ÷ L

i.e– it is the ratio of an increment in temperature to the length

Hence, Temperature gradient (Tg) has defined direction alongside with magnitude

And it is a vector quantity

Mass, work & Time are scalar quantity

There is an explanation video available .
