Detailed explanation-1: -When a frying pan containing cooking oil is kept for a long on a burning stove then cooking oil catches fire because the air on the pan is not available for this reason fire go upside so its temperature reaches upto igniation temperature and fire is on the pan. So option (b) is the correct answer.
Detailed explanation-2: -The temperature dependence of liquid viscosity is the phenomenon by which liquid viscosity tends to decrease (ore, alternatively, its fluidity tends to increase) as its temperature increase.
Detailed explanation-3: -Surface tension tends to decrease in liquids as temperatures rise, which led to a gradient in surface tension across the pan. The stronger tension toward the edges pulled the less cohesive oil at the centre outwards and deformed the surface of the layer.
Detailed explanation-4: -Heat causes proteins to fold in on themselves, or even to break down and form all new compounds. Once in their folded or rearranged form, they no longer stick.
