An unknown metal with a mass of 54.0 g required 773 J of energy in order to change its temperature from 63.0 C to 100.0 C. What is the identity of this metal?

Metal is copper.

Explanation:

Mass of a metal, m = 54 g

Heat energy required, Q = 773 J

The temperature changes from 63.0 °C to 100.0 °C.

We need to identify the metal. Heat required to raise the temperature is given by :

c is specific heat of the metal

We can identify the metal by finding its specific heat.

The metal is copper. Its specific heat is .

quartz

explanation:

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
