because of the heat lamp
hope this helps
Explanation:
Answer:
The two blocks have the same temperature
Explanation:
Given;
heat capacity of Aluminum = 0.9 J/g
heat capacity of copper = 0.35 J/g
thermal conductivity of copper = 385 W/(K m)
thermal conductivity of Aluminum = 205 W/(K m)
Based on the given data, it can be concluded that;
- Aluminum’s higher heat capacity means it does not get as hot when energy is shared between the two blocks, so the copper will be hotter
- Copper’s higher thermal conductivity will cause the aluminum to heat up compared to the copper
However, the two metallic blocks (aluminum block and a copper block), were allowed to achieve thermodynamic equilibrium, and as a result they will have the same temperature.
Therefore, the correct statement is "The two blocks have the same temperature".
Answer : Option D) Silicates.
Explanation : The minerals with the silicon-oxygen structures are classified as silicates.
As per the definition, A silicate is any member of a family which has anions consisting of silicon and oxygen, usually they have the general formula as [SiO].
It usually has a structure which has a central silicon ion which has a charge of (+4) while each oxygen has a charge of negative two (-2) and thus each silicon-oxygen bond is equal to one half (1/2) of the total bond energy of oxygen. Therefore, it confirms that the answer is Silicates.
Answer:
Al
Explanation:
Protons = mass number - neutrons 56-30 =26 closest is Al 27
Also in group 13 which loses 3 electrons to be +3
Answer:
Ductility
Explanation:
Ductility is the ability of a metal to be converted into a thin wire without getting break and loosing its hardness. The property of Ductility of a metal allows us to make a wider use of them. Some most ductile metals are gold, silver, copper etc. whereas some of the metals with very less ductility are tungsten, steel and other alloys as they are very hard to transform into a thin wire.
A metal with less ductility can be malleable as it can have the ability to be converted into a thin sheet. Not all the metals are ductile but some of them have high ductility, some have less and some of them are non ductile.
