Which one of the following is a vector quantity?
A
Temperature gradient
B
Mass
C
Work
D
Time
Verified Correct Answer: A.
Physical Principles & Numerical Solution
Temperature gradient(Tg) = DT \div L = T2 – T1 \div 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
