Volume percentage decreases with increases in temperature because _____.

Assertion : Molarity of a solution decreases with an increase of temperature Reason : As temperature increases volume of the solution increases.

Will the kinetic energy of molecules increase, decrease or remain same if : (i) the temperature is increased ? (ii) the pressure is decreased ? (iii) the volume is decreased ?

Assertion : A solid is floating in a liquid . If temperature is increased and expansion of solid is ignored, then fraction of volume immersed will increase. Reason : By increasing the temperature density of liquid will decrease.

As the volume increases with temperature, its density decreases.

At a constant pressure, what should be the percentage increase in the temperature in kelvin for a 10 % increase in the volume

At a constant pressure, what should be the percentage increase in the temperature in kelvin for a 10 % increase in the volume

A catalyst increases the rate of reaction because it : increases the activation energy, decreases the energy barrier for reaction, decreases the collision diameter, increases the temperature coefficient
