Answer:
The final temperature of the water is 22.44°C.
Explanation:
Heat lost by tin will be equal to heat gained by the water

Mass of tin = 
Specific heat capacity of tin = 
Initial temperature of the tin = 
Final temperature =
=T

Mass of water= 
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water =
=T

(Law of Conservation of energy)

On substituting all values:

we get, T = 22.44°C
The final temperature of the water is 22.44°C.

Answer:
<em>The valid conclusion is:</em>
- <u><em>D. the temperature of the object is increasing, while the temperature of the water is decreasing</em></u>
<u><em></em></u>
Explanation:
The answer choices are:
- <em>A. the temperature of the object is decreasing, while the temperature of the water is increasing</em>
- <em>B. the temperature of the object is decreasing, while the temperature of the water is decreasing</em>
- <em>C. the temperature of the object is increasing, while the temperature of the water is increasing</em>
- <em>D. the temperature of the object is increasing, while the temperature of the water is decreasing</em>

<h2>Solution</h2>

Thermal or heat energy always flows from the hotter substances to the cooler substances.
Thus, since the arrows show that the thermal energy is flowing from the water to the object, the water is losing thermal energy and the object is gaining thermal energy.
When an object gains thermal energy, and there is not involved a change of phase, the temperature of the object increases. Thus, the temperature of the object is increasing.
On the other hand, since water is losing thermal energy, and there is not involved a change of phase, the temperature of the water decreases.
Therefore, the correct conclusion is described by the option A:
- <em>A. the temperature of the object is decreasing, while the temperature of the water is increasing</em>
