Answer:
317.46 °C
Explanation:
The expression for the calculation of heat is shown below as:-
Where,
is the heat absorbed/released
m is the mass
C is the specific heat capacity
is the temperature change
Thus, given that:-
Mass of lead = 118.5 g
Specific heat = 0.129 J/g°C
Initial temperature = 10 °C
Final temperature = x °C
Q = 4700 J
So,
<u>Thus, the final temperature is:- 317.46 °C</u>
The correct answer is B.
Lowering of the freezing point can be a colligative property. The greatest concentration of mass of salt in the water will have what we call the lowest freezing point.
For example the least amount of water in the greatest amount of salt.
