If 200. g of water at 20°C absorbs 41 840 J of energy, what will its final temperature be? (Specific Heat of water is 4.184 J/g*C)

The final temperature will be

It is defined as the heat capacity of a sample of the substance divided by the mass of the sample.

Formula to calculate specific heat capacity:

where,

q = heat absorbed =

C = specific heat =

m = mass of water =

T₁= initial temperature =

To find:

T₂= final temperature =?

Now put all the given values in the above formula, we get:

Thus, the final temperature will be

The final temperature will be

Explanation:

To calculate the specific heat of substance during the reaction.

where,

q = heat absorbed =41840 J

c = specific heat =

m = mass of water  = 200 g

= final temperature =?

= initial temperature =

Now put all the given values in the above formula, we get:

Thus the final temperature will be

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

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
