Answer:
If it takes more energy to break the original bonds than is released when the new bonds are formed, then the net energy of the reaction is negative. This means that energy must be pumped into the system to keep the reaction going. Such reactions are known as endothermic.
Explanation:
<span>Following are important postulates of Kinetic theory of gases
1) Gases are made up of number of particles.
this particles behaves like hard and spherical objects, which are in constant state of motion.
2) The particles always travel in a straight line until they collide with another particle or the walls of the container.
3) Particles are of smaller size as compared to the distance between particles.
4) There exist minimal/no force of attraction between the gas particles neither there exist attractive interaction between the particles and the walls of the container.
5) Collisions between gas particles or with the walls of the container are elastic in nature.
Thus, statement a i.e. </span><span>Gas particles have a high force of attraction to one another or to the walls of the container contradicts the postulates of kinetic theory of gases</span>
Answer:
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... If that velocity is zero, then the object remains at rest.
Explanation:
Thats hard as hell just drop out of the class lol

I have had this question on a test before!! Hope this helps
