Answer:
Explanation:
= Mass of metal = 19 g
= Specific heat of the metal
= Temperature difference of the metal =
V = Volume of water = 150 mL =
= Density of water =
= Specific heat of the water = 4.186 J/g°C
= Temperature difference of the water =
Mass of water
Heat lost will be equal to the heat gained so we get
The specific heat of the metal is .
Answer:
Electrical conductivity in metals is a result of the movement of electrically charged particles. Because valence electrons are free to move, they can travel through the lattice that forms the physical structure of a metal.
