Answer:
Explanation:
Hello,
In this case, the increase in the temperature involves the addition of heat that is defined in terms of mass, heat capacity and temperature:
In this case, the heat capacity of iron is 0.450 J/(g*K), thus the heat results:
In such a way, since the temperature is increased heat is added, that is why it is positive.
Best regards.
The salivary amylase did not perform well if the pH becomes lower because it needs neutral pH for performing its functions.
<h3>Effect of pH on the enzyme</h3>
We can say that the salivary amylase did not perform their function very well within the stomach due to unfavourable environment such as lower pH. Due to lower pH, the enzyme structure is damaged so unable to perform its function so we can conclude that the salivary amylase did not perform well if the pH becomes lower.
