Question

Cooking oil appears to move more fluidly upon a frying pan after being heated on a stove. Why?  

a) None of these

b) Viscosity becomes zero as the temperature increases

c) Viscosity decreases with increase in temperature

d) Viscosity of oil increases with increase in temperature​

Answer 1

Answer:

C

is your answer

so what's your aim

Answer 2

Cooking oil appears to move more fluidly upon a frying pan after being heated on a stove because Viscosity decreases with an increase in temperature (option c).

The viscosity of liquids decreases with an increase in temperature, whereas in gases the viscosity increases with an increase in temperature.

The viscosity of a fluid depends on two factors:

• The intermolecular forces of cohesion among the fluid particles.
• The momentum of the particles due to their motion.

In the case of liquids, the momentum of particles is not significant as the particles are closely packed therefore with an increase in temperature the viscosity of the oil decreases.
