A 0.4 kg aluminum part increases its temperature by 25°C. How much thermal energy is transferred to the part by heat? (specific heat of aluminum = 900 J/kg•°C) help its on a tes i need hel

Explanation:

Hello.

In this case, since the energy involved in a heating process is computed via:

Whereas m is the mass (0.4 kg), Cp is the specific heat (900 J/kg•°C) and ΔT the temperature rise (25 °C), the required heat turns out:

It means that 9000 J of energy is transferred to attain that temperature raise.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
