Answer:
The mass is
Explanation:
From the question we are told that
The initial temperature is
The final temperature is
Generally the maximum heat produced by 1 Liter of natural gas is
So the amount of heat produced by 100 L is
=>
Generally given that the efficiency is
Then actual heat received by the water is
=>
=>
Converting to kcal
=>
Generally the specific heat of water is
Generally the heat received by the water is mathematically represented as
=>
=>
The temperature inside the copper rod varies linearly with the distance from the hot end of the rod. This means that we can find the temperature at 23 cm (let's call it 'point A') from the cool end by solving a linear proportion.
The temperature difference between the two ends of the rod is
and this corresponds to a length of 81 cm. Therefore, we can write:
from which we find
This is not the final answer actually; this is the temperature difference between the cool end and point A. So, the temperature at point A is
