Consider the chemical reaction in equilibrium. H2 + 12 + heat → 2H1
What will happen to the chemical equilibrium if the temperature of the system is increased?
The direction of the chemical equilibrium will shift to the right, favoring the forward reaction.
O The chemical equilibrium will not be affected by an increase in temperature.
The direction of the chemical equilibrium will shift to the left, favoring the reverse reaction.
O The chemical equilibrium will be lost permanently with a change of temperature.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

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.
