Answer:
68000J/kg
Explanation:
Given parameters:
Mass of the substance = 0.5kg
Quantity of heat transferred to the body = 34000J
Unknown:
Specific latent heat of fusion = ?
Solution:
The specific latent heat is usually involve in phase changes;
H = mL
H is the quantity of heat supplied
m is the mass
L is the specific latent heat
Insert the parameters and solve;
34000 = 0.5 x L
L = 
= 68000J/kg
Silicate. It is silica, SiO2 with contaminants such as Fe3+ that give it color. technically it is a tecto-silicate.<span>

Answer:
True or False
Answer - True
Explanation:
The mantle convection clearly describes how the mantle moves, transferring heat from the white-hot core to the lithosphere. The mantle is usually being heated below and the cooling happens above and the general temperature of the area gets dropped over a long period of time.
Hot buoyant Magma is being transferred through convection currents, to the lithosphere at the plate boundaries and hot spots. Also, convection current moves cooler materials from the crust to the interior of the earth through a process that is widely known as subduction.
