Answer 1

temperature is a scalar quantity.
pressure is a scalar quantity.
time is a scalar quantity.
power is a scalar quantity.
energy is a scalar quantity.
gravitational potential is scalar quantity .
charge is a scalar quantity

Answer 2

Temperature: scalar quantity
Pressure: scalar quantity
Impulse: Vector quantity
Time : scalr quantity
Power : scalar quantity
Total path : scalar quantity
Length : scalar quantity
Energy : scalar quantity
Gravitational potential : scalar quantity
Coefficient of friction : scalar quantity
Charge : scalar quantity.

Hence, only impulse is vector quantity.
