What does the specific heat for a substance indicate? A. the heat released when 1 gram of the substance burns B. the amount of h
2 answers:
Answer:
B. the amount of heat required to increase the temperature of 1 gram by 1°C
Explanation:
The heat required by a substance having mass m to raise the temperature of it by ΔT.
Q = m c ΔT
where c is the specific heat of the substance.
Specific heat for a substance is the amount of heat required to increase the temperature of 1 gram by 1°C.
For example, the specific heat capacity of water is 4.186 J/g°C. This means 4.186 J is required to raise the temperature of 1 g of water by 1°C.

Answer:
Explanation:
From the information given:
oxidation of oxidized solution takes place at 950° C
For wet oxidation:
The linear and parabolic coefficient can be computed as:
Using and
values obtained from the graph:
Thus;
So, the initial time required to grow oxidation is expressed as:
∴
NOW;
Thus; since we will consider the positive sign, the initial thickness is ;
≅ 0.261 μm
