I have a doubt on heat and temperature. I need help with this science question and here the question: The water in a lake just reached freezing point temperature. Why can’t you go ice skating on it yet?

you can't go ice skating on it because if it just reached the temp then you need to wait for about 2 hours

Explanation:

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
