Which one of the following is a vector quantity?
-
A.
Temperature gradient -
B.
Mass -
C.
Work -
D.
Time
Correct Answer: Option 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
