Answer:
<h2>C) internal combustion engine</h2>
Explanation:
When an object absorbs an amount of energy equal to Q, its temperature raises by
following the formula
where m is the mass of the object and
is the specific heat capacity of the material.
In our problem, we have
,
and
, so we can re-arrange the formula and substitute the numbers to find the specific heat capacity of the metal:
Answer:
23.585°C
Explanation:
500W/s = 500J/s half a minute = 30s
30 x 500J = 15000J in half a minute
the specific heat of water is 4.184J/gC
Use the specific heat formula:
(20C)(1kg)(4184J/kgC)= 83680J
83680J + 15000J = 98680J
98680J = (x)(1kg)(4184J/kgC)
98680J = 4184x
Divide
x = 23.585°C
