Answer:
Density = 2.5 g/cm³ , The metal is aluminium.
Explanation:
Density is defined as the ratio of the mass and the volume
Thus,
Given that:
Mass = 612 grams
Volume = 245 cm³
Thus, Density is:
<u>Density = 2.5 g/cm³</u>
Metals are shiny with high density.
<u><em>The density of aluminium falls is approx 2.6 g/cm³ and not other metal's density falls in this range. </em></u>
<u><em>The metal is aluminium.</em></u>
<u><em></em></u>
Answer:
Graphite is an electrical conductor, hence useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.
Sodium’s combination with water creates a colourless result of sodium hydroxide (NaOH) and hydrogen gas (H2). ... The reaction is exothermic. During the reaction, the sodium metal become very hot, to the point where it can catch fire and burns with a characteristic orange colour.
Answer:
if you drop a water balloon onto the ground, its kinetic energy is converted mostly to thermal energy. If the balloon weighs 1 kilogram and you drop it from about 2 meters, it will heat up by less.
Explanation:
As you say, kinetic energy of large objects can be converted into this thermal energy. For example, if you drop a water balloon onto the ground, its kinetic energy is converted mostly to thermal energy. If the balloon weighs 1 kilogram and you drop it from about 2 meters, it will heat up by less than.
