Answer:
Option D. All of these
Explanation:
The creativity involves the process of using the brain to use new or existing knowledge to overcome a problem. This sometimes involves starting something purely from stretch or using the existing design laws and theories to solve a problem. As a result, the correct option is D as all of the above applies.
Answer: B) The rate of reaction
Explanation: Rate of reaction describes the speed at which the reactants of the reaction are getting converted into the products with respect to time.
The equilibrium explains that how much concentration of reactant is in equilibrium with the product.
Solution concentration is the number of moles of solution divided by volume.
The catalyst is the substance which increases the rate of the reaction which bringing any change in other things.
Answer:
C. cooler than both the crust and the core
Explanation:
It is observed that at the mantle, temperatures range from estimatedly 200 °C (392 °F) around the upper boundary with the crust to approximately 4,000 °C (7,230 °F) at the core-mantle boundary.
So we can say the mantle is cooler than both the crust and the core.
As the momentum of molecules is reversed during collisions with the walls of a container they exert a force on the wall. The net result of the force per unit area on the wall is pressure.
Note that the following is based upon a number of assumptions - the assumptions of kinetic theory,
Molecules move with constant velocity until they collide with the wall. During the collision their momentum perpendicular to the wall is reversed. From Newton's second law of motion a resultant force (acting on molecules) is necessary for that momentum reversal to have happened. The wall provides the force. From newton's third law of motion the molecule exerted a force on the wall.
The sum of all the forces exerted on the wall by all the molecules that collide at one time divided by the area of the wall gives a pressure on the wall - the pressure of the gas.
