The law conservation of mass, because part of the mass can be converted into energy
also, the elements are changing during nuclear reactions, new elements are formed
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
Not necessarily, rain needs some mechanism such as instability of vertical air movement..
Its both A and C because both A and C have only one type each so it can only be those two :)
If you think of it endothermic is when there is energy needed for the reaction to occur and exothermic is when the reaction releases energy
