How Does Water Content in Ice Affect Its Latent Heat of Fusion Value?

AI Thread Summary
The discussion revolves around the impact of water content in ice on its latent heat of fusion value. A school experiment revealed that the measured value was smaller than the standard due to pre-melting of the ice. Participants agree that the presence of melted water requires less energy to further melt the remaining ice, leading to a lower value. The logic behind this conclusion is affirmed, although some participants acknowledge their status as students and seek further confirmation. Overall, the experiment highlights the complexities in measuring latent heat of fusion in real-world conditions.

We did a calorimeter experiment in my school however the teacher warned us that the latent heat of fusion of ice value will be different from the standard value because the ice has water in it and because the ice melts little before actually doing the experiment. However my question is which way should the number be different should it be a larger or smaller value? I got a smaller value in my experiment but I do not know how to explain why it is smaller.

I think it should be smaller because if some of the ice is already melted then less energy is necessary to melt the ice therefore a smaller number. Please make sure my logic is correct though?

To me your logic is right. However I'm still a student.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
