A 30.73 g 30.73 g sample of a substance is initially at 20.8 ° C. 20.8 °C. After absorbing 2813 J 2813 J of heat, the temperature of the substance is 163.2 ° C. 163.2 °C. What is the specific heat ( c c ) of the substance?

Explanation:

Hello,

In this case, the following hear+t equation is taken in account in terms of the required specific heat:

Thus, as the the heat is absorbed it is taken positive, therefore, the heat capacity results:

Best regards.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
