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>
Answer:
Scientific Method - steps to use when doing an experiment.
1. Make a question
2. Do some Research
3. Hypothesis - make a guess
4. Test and Collect Data
5. A conclusion
Answer: B.
Explanation:
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
