Answer:
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 
.
Mantle convention, convection cells in the mantle, and produces horizontal motion of mantle material close to the Earth surface.
Answer: Intensive physical property
Explanation: Color is an intensive physical property since intensive properties are properties that stay the same no matter the amount of the substance is present. Blood is still red whether or not you have 2 liters of it or 4 liters.
Answer: See explanation
Explanation:
1. Separation of charges in an object without touching it is (charging by induction).
2. The work done moving a positive test charge between two points in an electric field divided by the magnitude of the test charge is the electric (potential difference).
3. An electric (conductor) is a material through which charges move about easily. (Charging by conduction) is giving a neutral object a charge by touching it with a charged object.
4. A material through which electrical charges does not move easily is an electrical (insulator).
5. The lines providing a picture of the size and strength of the field around a charged object are called the (electric field lines).
6. The property of the space around a charged object that exerts a force on other charged objects is the (electric field).
7. A device that helps determine charge using pieces of metal foil is an (electroscope).
8. The magnitude of the charge of an electron is the (elementary charge)
