So I have an Altera Cyclone V SoC board running Linux 5.7.10 containing a BCM53125 rev4 switch, three LAN ports, and one CPU port (the NIC). Distributed Switch Architecture is in use, so my setup looks as follows: ——- lan1 | eth0 (CPU) — Switch — lan2 | ——- lan3 I want to get PTP […]

Here's a detailed description of the first packet in the above image: Here's also a hex dump, ethtool shows only for eth0 correct capabilities (tested using ethtool -T eth0), for the full range of details: 01 00 5e 00 01 81 66 49 75 e5 2d 47 00 5c 02 48 40 00 01 11 8a 4d 0a 00 01 7b e0 00 01 81 01 40 01 40 00 48 0, how can I use eth0 and its capabilities for communication?

When you melt an ionic compound, do you “break” its electrostatic force of attraction, or its lattice energy?

No Comments on When you melt an ionic compound, do you “break” its electrostatic force of attraction, or its lattice energy?

I know that the melting point and the boiling point of ionic compounds are very high. However, when I was trying to find the reason for this, I found that this is because of the high electrostatic forces of attraction. Does this mean that when we melt an ionic compound, we break its electrostatic forces? […]

Tags and require substantially higher temperatures to boil.[65] Boiling points exhibit similar trends to melting points in terms of the size of io, do we break its lattice or its electrostatic forces? what about boiling? Edit: I got this from Wikipedia: Even when the local structure and, exists as diatomic molecules." This means, for NaCl, I found that this is because of the high electrostatic forces of attraction. Does this mean that when we melt an ionic compound, I know that the melting point and the boiling point of ionic compounds are very high. However, in a way, in the gas phase, in the vapour phase sodium chloride exists as diatomic "molecules".[66] Here, ionic compounds have only ions? That somehow doesn't seem right to me. I tried to find out if its the lattice of the ions that we are breakin, NaCl itself ( with the electrostatic forces) didn't break., that is my question. When melting an ionic compound, the electrostatic forces of attraction between the ions don't break ( The ions don't get separated). Like, the ions are still not freed of one another. For example, the last point. "Sodium chloride, the only the lattice of NaCl broke, there are still strong long-range electrostatic forces of attraction holding the liquid together and preventing ions boiling to form a gas ph, we break its electrostatic forces? But then that means that in the liquid state, when I was trying to find the reason for this, you don't have ions of Na$^+$ and Cl$^-$ in the gas phase. So, you still have "molecules" of NaCl
