A barometer is the answer
Answer : The heat energy needed would be, 6486.5125 J
Explanation :
To calculate the change in temperature, we use the equation:
where,
q = heat needed = ?
m = mass of aluminum = 223 g
c = specific heat capacity of aluminum = 
= change in temperature
= initial temperature = 
= final temperature = 
Putting values in above equation, we get:
Therefore, the heat energy needed would be, 6486.5125 J
I will Answer it and get back to u in the the comment section
C-12 and C-13 are isotopes of the element carbon. Since they are both of the same element, they have the same number of protons. The number that follows the C indicates the number of neutrons. Isotopes are variations of the element with different number of neutrons. C-12 shows that that variation of carbon has 6 protons and 6 neutrons for a total mass of 12. C-13 shows that it has 6 protons but 7 neutrons for a total mass of 13
A major concept to remember: “Nature seeks the lowest energy state”. In the lowest energy state, things are most stable...less likely to change. The following information that talks about stability is all based on the nucleus tending towards the lowest energy state. Stable atoms have low energy states.
