<u>Answer:</u> The smallest temperature change is shown by water.
<u>Explanation:</u>
To calculate the heat absorbed or released, we use the equation:
......(1)
where,
q = heat absorbed = 200.0 J
m = mass of the substance
C = specific heat of substance
= change in temperature
As, the same amount of heat is getting absorbed in all the cases. So, the change in temperature will depend on the product of mass and specific heat.
For the given options:
- <u>Option a:</u> 50.0 g Fe,
We are given:
Putting values in equation 1, we get:
Change in temperature = 8.99°C
- <u>Option b:</u> 50.0 g water,
We are given:
Putting values in equation 1, we get:
Change in temperature = 0.96°C
- <u>Option b:</u> 25.0 g Pb,
We are given:
Putting values in equation 1, we get:
Change in temperature = 62.5°C
- <u>Option d:</u> 25.0 g Ag,
We are given:
Putting values in equation 1, we get:
Change in temperature = 34.04°C
- <u>Option e:</u> 25.0 g granite,
We are given:
Putting values in equation 1, we get:
Change in temperature = 10.13°C
Hence, the smallest temperature change is shown by water.
