Why do we need to measure time ??

hehehe me too ❤️.·´¯`(>▂<)´¯`·.

We need to measure the time to keep a track of our daily activities. For example, having an appointment with a doctor, scheduling a meeting with someone, reaching the office or school or college in time, etc., for all such activities time measurement is necessary.

Explanation:

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
