Question

WHAT IS EFFECT OF TEMPERATURE ON THE SOLUBILITY OF SOLIDS IN LIQUIDS

Answer 1

A car of mass 800kg is travelling with a velocity of 20 m/s. When brakes are applied,it stops after travelling a distance of 8 meters. Find Retardation and Retarding force? A force of 2N acting on a body changes its velocity uniformly from 2 m/s to 5 m/s in 10s. Calculate the mass of the body. Calculate the change in momentum of a body weighing 5kg when its velocity decreases from 20m/s to 5 m/s?(Hint: Calculate P2- P1) What would be force required to produce an acceleration of 2m/s2 on a body of mass 12kg? A ball freely falling from a tower of height 5 m . How much momentum does it transfer to the floor if its mass is 5kg?

Answer 2

Answer:

Hello mate, here is the answer!!

Explanation:

If the heat given off in the dissolving reaction is less than the heat required to break apart the solid, the net dissolving reaction is endothermic. The addition of more heat facilitates the dissolving reaction by providing energy to break bonds in the solid. This is the most common situation where an increase in temperature produces an increase in solubility for solids.
