Answer:
Ok so the answer for 9 is
x/6=4
x=24
Explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Answer:
Explanation:
Enertia is an integral part of Newton's first law of motion.
It is the tendency of an object to <u>stay at rest</u> or <u>to continue moving</u> until and unless <u>any external unbalanced force</u>, (like, applied force or force of tension or frictional force ) is applied to either move it from rest or change its speed(in other words, accelerate it!!).
Example below, is of ball at rest (fig1) and if this ball is moving straight on a frictionless surface(like ice) it will keep moving!! until, we push it or pull it.
Answer:
B
Explanation:
because B has a lower bp it needs less time and energy to turn into vapour and is collected into the condenser first
Answer: The increase in solubility or the rate of dissolving process of a gaseous solute in a liquid solvent is due to following:
- Increasing agitation
- Increasing temperature
- Increasing solute's partial pressure over the solvent
- Increasing solute's surface area
Explanation:
When agitation is increased then there will occur an increase in kinetic energy of the molecules of a substance. As a result, more number of collisions will take place due to which more amount of solute will dissolve into the solvent.
Similarly, increasing the temperature will further increase the kinetic energy of molecules. Hence, this will lead to more solubility of gaseous solute into the liquid solvent.
As solubility of a gas is directly proportional to the pressure of the gas above surface of the solution. So, an increase in solute's partial pressure over solvent will also lead to an increase in solubility of gaseous solute into liquid solvent.
When surface area of solute is increased then there will be more solute particles available for reaction. Hence, more collisions will take place. As a result, rate of reaction is more due to which there will be an increase in solubility.
Thus, we can conclude that the increase in solubility or the rate of dissolving process of a gaseous solute in a liquid solvent is due to following:
- Increasing agitation
- Increasing temperature
- Increasing solute's partial pressure over the solvent
- Increasing solute's surface area
