What will be the new volume of a 250 ml sample of gas at 300 k and 1 atm if heated to 350 k at 1 atm?

The   new volume of a 250  Ml   sample of gas at 300k  and  1atm  if  heated to 350 k  at  1 atm  is  291.67  Ml

calculation

This  is  solved  using  the  Charles  law formula  since the  pressure  is constant.

that is V1/T1 = V2/T2  where,

V1 =250 ml

T1=300  K

V2=?

T2= 350 k

by making V2 the subject   of  the formula  by  multiplying  both side by T2

V2= T2V1/T1

V2= (350 K x 250 ml) / 300K =291.67 Ml

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.
