What is the final pressure (in mm Hg) inside the car if the sun heats the car from 20 Celsius to 55 Celsius. The initial pressure was 760 mm Hg. Assume the volume of the car is 2600 Liters.

851 mmHg

Explanation:

Using pressure law equation as follows:

P1/T1= P2/T2

Where;

P1 = initial pressure (mmHg)

V2 = final pressure (mmHg)

P1 = initial temperature (K)

T2 = final temperature (K)

According to the information provided in this question,

P1 = 760mmHg

P2 = ?

T1 = 20°C = 20 + 273 = 293K

T2 = 55°C = 55 + 273 = 328K

Using P1/T1= P2/T2

760/293 = P2/328

Cross multiply

293 × P2 = 760 × 328

293P2 = 249280

P2 = 249280 ÷ 293

P2 = 850.78

Approximately, P2 = 851 mmHg.

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.
