User mode means that the computer is executing instructions in some user's program. Kernel mode means that computer is executing instructions in the kernel. In kernel mode, the system has some more power. But is user mode, certain restrictions apply. If you are running a program and you issue a system call, the computer must switch from user mode to kernel mode to process your system call.
"De-mountable volume" is not a standard term and it's not super clear what that is supposed to mean. It could mean any volume that can be unmounted via the umount command. But some OS versions have a way to "force" a umount. In theory, every volume can be umount'ed except the root volume itself.
My guess is that removable media is what they're getting at (and that this is homework).
