If 0.871 g of a metal thought to be gold uses 1.47 J of energy to heat it from 25.2°C to 38.3 degrees * C . Confirm that the metal is gold. The specific heat of gold is .201J / g Your work must be shown to justify your answer.

Explanation:

Given that,

Mass of metal, m = 0.871 g

Heat, Q = 1.47 J

The temperature increases from 25.2°C to 38.3°C. We know that, heat released is given by :

Hence, the metal is made up of gold.

that is probably false!

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.
