A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.
Hope this is what you mean be hot spot!

Answer:
5.4 tonnes.
Explanation:
The first step is to find the molar mass of Al2O3. Aluminum has a molar mass of about 27 and oxygen has a molar mass of about 16, so 2(27)+3(16)= 102g/mol=0.102kg/mol. 10200kg/0.102kg/mol=100,000 moles of Al2O3 in 10.2 tonnes. Multiplying this by the molar mass of the two aluminums, you get a total of 54*100,000=5400000g=5400kg=5.4 tonnes. Hope this helps!

Explanation:
The value that describe temperature and pressure (STP) is 273.15 K and 101.3 KPa (answer D)
<em><u>Explanation</u></em>
International union of pure and applied chemistry ( IUPAC) established standard temperature and pressure (STP) as below,
temperature 0°c which is the same as 273.15 K
Pressure = 1 atm which is the same = 101.325 KPa or 1.01325 bar
