Question

What is the effect of temp. on molality and morality? 1mark

Answer 1

molarity is affected by temp because it depends upon volume of the solution. on increasing temp, density decreases and volume increases ,hence molarity decreases.
No effect of temp on molality. 

Answer 2

Answer:

But temperature has no effect on mass. So with change in temperature, molarity also changes. But there is no effect of temperature on molality. For example, with increase in temperature, volume will increase and then molarity will decreases.
