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>
Equal. Good luck with other questions!
Since the mass of a single popcorn kernel is not given, lets us assume that it is 1 gram
Now:
1 mole of popcorn kernels contain kernels
Since:
1 kernel weighs 1 gram
Then,
kernels would weigh grams
Answer:
nuclear
Explanation:
This is because when the protons and neutrons split the energy being released is heat, also known as nuclear fission.
As the temperature increases, the speed of gas molecules increases.
