<span>These gas molecules are much smaller than the distance between them.
</span><span>So, most of the volume of a gas is therefore empty space.
</span><span>There is no force of attraction between gas particles or between the particles and the walls of the container.
Because there is a large amount of empty space between gas molecules,the gas has property of low density.</span>
the correct answer is option d.
6.67*10-3 hrs
Answer:
-1071 Joules
Explanation:
The Joule was introduced as the SI unit for energy in 1925. One calorie is equal to approximately 4.184 joules(J). This is a conversion factor that we can write two ways:
(1cal/4.184J) or (4.184J/1cal)
(265 cal)*(4.184J/1cal) = 1071 J
Since the energy is leaving the system, it should be written with a minus sign: -1071J
