Answer: is<u><em> Second Law of Thermodynamics (conduction)</em></u>.
john stirs the hot soup with a spoon the heat travels up the spoon to his hand is due to the basic law of conduction, also known as the second law of thermodynamics . Heat always travels from hot things toward the cold things, is proved by the phenomena that a cup of tea always get cold, and and a cold dessert or ice cream always melts. Its not possible that the cup of tea become boiling by itself and similarly an ice cream getting frozen on its own in on a hot day. To understand this point there are three ways in which heat can travel namely, conduction, radiation and convection. The process due to heat travels up to the spoon from the soup towards john's hand is called conduction. Conduction is the process in which heat travels between two solid things that are at different temperature. Cooking soup in a saucepan with a metal spoon will make your fingers hot because of the conduction of heat, that travels through the boiling soup pan through metal spoon towards your hand.
It's the angle made by the incident ray when it's perpendicular to the surface. (Perpendicular lines are the lines that form a graph or like a 90-degree angle)
Explanation:
Sky appears blue because of Scattering.Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.
